[0024] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0025] like Figure 1 , Figure 2As shown, an air-conditioning ground air supply device described in the present invention is applied to underground scenes and connected to underground air-conditioning equipment. Its purpose is to change the traditional air outlet method and achieve the air supply effect of ground air outlet. Specifically, the air-conditioning ground air supply device includes three ventilation ducts 1, embedded sleeves 2 and air volume adjustment devices 3. The three ventilation ducts 1 are installed under the floor. The left air outlet of the three ventilation ducts 1 is connected to the main air duct of the basement. The main air duct of the basement is connected to the underground air-conditioning equipment. The upper air outlet of the three ventilation ducts 1 is connected to the embedded sleeve 2. The embedded sleeve 2 is embedded in the floor 4 and connected to the bottom of the air volume adjustment device 3. The air volume adjustment device 3 is fixed on the surface of the floor 4. The air-conditioned air is blown into the room from the underground through the three ventilation ducts 1, the embedded sleeve 2 and the air volume adjustment device 3 in sequence. Specifically, fireproof mud (not shown in the figure) is embedded between the embedded sleeve 2 and the floor slab 4. The fireproof mud can be used to fill the gap between the embedded sleeve 2 and the base plate, and also to protect the embedded sleeve 2 from corrosion. In the event of a fire, it can also be used to prevent the spread of fire and prevent the spread of smoke.

[0026] Furthermore, if Figure 1 As shown, the embedded sleeve 2 is provided with a first inner pressure ring 21, and the upper air outlet of the three-ventilation duct 1 is provided with a second inner pressure ring 12. The first inner pressure ring 21 matches the second inner pressure ring 12, so that the upper air outlet of the three-ventilation duct 1 can be fixedly sleeved in the embedded sleeve 2. Specifically, the first inner pressure ring 21 is an inner pressure type sealing ring integrally provided with the embedded sleeve 2, and the second inner pressure ring 12 is an inner pressure type sealing ring integrally provided with the upper air outlet of the three-ventilation duct 1. The radius of the arc corresponding to the first inner pressure ring 21 is greater than the radius of the arc corresponding to the second inner pressure ring 12, so as to ensure that when the second inner pressure ring 12 moves to align with the position of the first inner pressure ring 21, the first inner pressure ring 21 can clamp the second inner pressure ring 12, thereby ensuring that the upper air outlet of the three-ventilation duct 1 can be fixed in the embedded sleeve 2, thereby ensuring the sealing of the connection between the three-ventilation duct 1 and the embedded sleeve 2. It should be emphasized that the internal pressure type sealing ring is an inwardly concave sealing ring with a certain elasticity, and the upper air outlet of the three-ventilation duct 1 has a smaller elasticity than the internal pressure type sealing ring, so that under the action of a certain pulling force, the upper air outlet of the three-ventilation duct 1 can move normally in the embedded sleeve 2.

[0027] When it is necessary to connect the three-way ventilation duct 1 and the embedded sleeve 2, the upper air outlet of the three-way ventilation duct 1 is placed in the embedded sleeve 2 and moved upward until the second inner pressure ring 2 moves to the position corresponding to the first inner pressure ring 21. At this time, if the three-way ventilation duct 1 and the embedded sleeve 2 are relatively displaced again, the resistance can be obviously increased, thereby achieving a fixed connection between the three-way ventilation duct 1 and the embedded sleeve 2. At the same time, it should be noted that in order to prevent friction damage and embedding difficulties between the embedded sleeve 2 and the floor slab 4, the external pressure type outward protruding sealing ring is not selected.

[0028] Furthermore, if Figure 1 As shown, in the first embodiment of the present invention, a 3mm thick steel plate 5 is integrally provided on the top of the embedded sleeve 2, the end face of the steel plate 5 is rectangular and a through hole corresponding to the embedded sleeve 2 is provided on the steel plate 5, and the through hole on the steel plate 5 is used to allow air conditioning gas to enter the air volume regulating device 3 from the embedded sleeve 2. Specifically, the steel plate 5 is placed on the floor 4 and the bottom surface of the steel plate 5 is in contact with the top surface of the floor 4. The air volume regulating device 3 is placed above the steel plate 5. The steel plate 5 and the air volume regulating device are detachably connected by bolts or other fastening components. The steel plate 5 is used to prevent the embedded sleeve 2 from slipping, seal the connection between the embedded sleeve 2 and the floor 4, and provide a flat installation scene for the air volume regulating device 3. It should be noted that at this time, the top surface of the air volume regulating device 3 is higher than the surface of the floor 4, so as to facilitate the disassembly and maintenance of the air volume regulating device 3.

[0029] Furthermore, if Figure 1 As shown, the air volume regulating device 3 includes a herringbone regulating valve 31 and rainproof louvers 32, the steel plate 5 is fixedly connected to the herringbone regulating valve 31, the rainproof louvers 32 are fixedly installed above the herringbone regulating valve 31, the rainproof louvers 32 are connected to an air volume regulating roller 33 for adjusting the herringbone regulating valve 31, and the air volume regulating roller 33 is rotatably connected to the rainproof louvers 32 through a bearing. Specifically, the herringbone regulating valve 31 includes a fan blade and a gear fixedly connected to the end of the fan blade, the fan blade and the gear are synchronously driven, one end of the air volume adjustment roller 33 is installed on the outside of the rainproof louver 32, and the other end passes through the rainproof louver 32 and is connected to the herringbone regulating valve 31 through a transmission gear, the transmission tooth is installed inside the rainproof louver 32, the middle part of the transmission gear is sleeved on the end of the air volume adjustment roller 33 and fixedly connected thereto, and the lower end of the transmission gear is meshed with the gear in the herringbone regulating valve 31, so that when the air volume adjustment roller 33 rotates, the air volume adjustment roller 33 can drive the gear and fan blade on the herringbone regulating valve 31 through the transmission gear, thereby realizing the control of the opening and closing size of the herringbone regulating valve 31, so as to achieve the effect of controlling the ground air supply volume.

[0030] Furthermore, if Figure 1As shown, the air-conditioning floor air supply device also includes a water receiving tray 6 that is detachably connected to the lower air outlet of the three-ventilation duct 1. The water receiving tray 6 is a round tube with a receiving tray at the bottom. The water receiving tray 6 is used to collect condensed water that flows down or drips in the air duct for easy discharge. Four buckle rings 11 are distributed around the outer wall of the lower air outlet of the three-ventilation duct 1, and four buckles 61 are distributed around the outer wall above the water receiving tray 6. The buckle rings 11 correspond to and match the buckles 61. In this embodiment, the buckle with model J001 in the prior art can be selected. Specifically, the four buckle rings 11 are evenly distributed around the outer wall of the lower air outlet of the three-ventilation duct 1 and their heights are equal. The four buckles 61 are arranged around the outer wall above the water receiving tray 6 corresponding to the positions of the buckle rings 11, thereby ensuring that the three-ventilation duct 1 and the water receiving tray 6 can be normally connected. It should be added that, in this embodiment, the inner diameter of the top of the water receiving tray 6 is equal to the inner diameter of the bottom of the downwind outlet of the three-way ventilation duct 1, so that the top of the water receiving tray 6 can be partially mounted on the downwind outlet of the three-way ventilation duct 1, thereby facilitating the discharge of condensed water.

[0031] Furthermore, if Figure 1 As shown, an inner pressure bend 62 is provided in the middle of the water receiving pan 6, and the inner pressure bend 62 is a circular ring recessed into the water receiving pan 6. A filter screen 63 is fixed on the inner pressure bend 62 for filtering debris dropped on the ground. A float valve 64 and a condensate pipe 65 connected to the float valve 64 are installed below the filter screen 63. Specifically, one end of the condensate pipe 65 is arranged in the water receiving pan 6, and the connection between the condensate pipe 65 and the water receiving pan 6 is fixedly connected by waterproof adhesive or other adhesive components and fastening components. The other end of the condensate pipe 65 extends out of the water receiving pan 6 and is connected to the outside. A sealing component, such as a sealing ring, is also installed at the connection between the water receiving pan 6 and the condensate pipe 65. The condensate pipe 65 is used to discharge the condensate collected in the water receiving pan 6 and the water dropped on the ground. The ball of the float valve 64 is blocked at the pipe mouth of the condensate pipe 65, and the float valve 64 is connected to the bottom of the water receiving pan 6 to control the discharge of condensate.

[0032] Furthermore, if Figure 1 As shown, the condensing water pipe 65 and the outer wall of the three-way ventilation duct 1 are both pasted with thermal insulation cotton. Specifically, the condensing water pipe 65 and the outer wall of the three-way ventilation duct 1 are both pasted with rubber-plastic thermal insulation cotton, the rubber-plastic thermal insulation cotton is 30 mm thick, and the inner surface of the rubber-plastic thermal insulation cotton is tightly fitted to the outer surface of the condensing water pipe 65 and the three-way ventilation duct 1, thereby effectively preventing the loss of cold or heat.

[0033] Furthermore, if Figure 2As shown, in the second embodiment of the present invention, a 3mm thick steel plate 5 is integrally provided on the top of the embedded sleeve 2, and the steel plate 5 is also embedded in the floor 4, and there is a certain distance between the top surface of the steel plate 5 and the top surface of the floor 4. An air volume adjustment device 3 is placed above the steel plate 5. When the air volume adjustment device 3 is completely installed on the steel plate 5, the top surface of the air volume adjustment device 3 is flush with the surface of the floor 4, so as to facilitate the walking of personnel and improve the aesthetics. At the same time, it should be supplemented that a groove for the rotation of the air volume adjustment roller 33 is also provided on the floor 4. When the air volume adjustment roller 33 rotates to the highest point, the top surface of the air volume adjustment roller 33 is flush with the top surface of the floor 4 or slightly higher than the top surface of the floor 4, so as to ensure that while facilitating the adjustment of the rotation of the air volume adjustment roller 33, it avoids affecting the walking of personnel.

[0034] The working process of the present invention is as follows:

[0035] During operation, the air conditioning wind in the main air duct of the basement enters the three-way pipe and is blown into the room from underground through the embedded sleeve 2 and the air volume adjustment device 3, thereby solving the problems of the upper air supply blocking the line of sight and the side air supply blowing directly on the head. At the same time, the herringbone regulating valve 31 is used to control the size of the upward air supply volume, and can be adjusted by the air volume adjustment roller 33 on the top rainproof shutter 32. The rainproof shutter 32 can effectively prevent the debris on the ground from entering the pipeline, thereby increasing the practicality of the present invention. When there are still debris on the ground accidentally falling into the embedded three-way air duct 1, the water receiving tray 6 can effectively filter the fallen debris, and the water receiving tray 6 can be removed at any time to clean the internal debris. At the same time, a float valve 64 is provided at the connection between the water receiving tray 6 and the condensation water pipe 65. When a certain amount of water is stored in the water receiving tray 6, the float valve 64 will automatically open, so that the water in the water receiving tray 6 is discharged through the condensation water pipe 65. After the water in the water receiving tray 6 is discharged, the float valve 64 is closed to achieve the effect of ensuring sealing and preventing cold loss. At the same time, it should be added that the design of applying fireproof mud to tighten and seal the embedded sleeve 2 and the sealing ring between the three-way ventilation duct 1 and the embedded sleeve 2 makes it possible to effectively avoid the loss of cold air, thereby making the working efficiency of the device higher and more stable.

[0036] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners, and any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of the present invention.
