Description

Technical Field

[0001] This application relates to the field of air supply equipment, and in particular to a fresh air cooling device for enclosed spaces. Background Technology

[0002] As an important component of industrial water storage systems, underground water storage tanks can experience water quality deterioration due to the growth of algae, bacteria, and other microorganisms on their walls during long-term water storage, affecting water safety. To ensure water cleanliness, underground water storage tanks require regular cleaning to remove sediment and microorganisms and maintain their normal water storage function.

[0003] Currently, the cleaning of underground water storage tanks is mostly done manually. In actual cleaning, construction workers need to enter the water storage tank and use handheld high-pressure water guns to rinse the tank walls and bottom, flushing impurities to the bottom of the tank, and then draining the wastewater containing impurities through the drainage system.

[0004] Regarding the aforementioned technologies, the relatively enclosed internal space of underground water storage tanks results in poor ventilation and high temperatures. During actual cleaning operations, workers are highly susceptible to safety issues such as dizziness and heatstroke due to oxygen deficiency and high temperatures, typically making prolonged work impossible. Therefore, there is room for improvement. Utility Model Content

[0005] In order to improve the working environment during the cleaning of underground water storage tanks, this application provides a closed space fresh air cooling device.

[0006] This application provides a closed-space fresh air cooling device, which adopts the following technical solution: A closed-space fresh air cooling device includes an air supply component and a support component; The air supply assembly includes a blower, and the blower outlet is connected to an air supply hose; a base is provided at the bottom of the blower, and several main casters are installed at the bottom of the base; The support assembly includes several brackets for supporting the air supply hose; a limiting member is connected to the top of the bracket, the limiting member is bent to form a U-shaped limiting groove, the U-shaped limiting groove is used for the air supply hose to be inserted.

[0007] By adopting the above technical solution, when cleaning the underground water storage tank, the blower is moved to a suitable position using the base and main casters, the air supply hose is moved into the underground water storage tank, and the air supply hose is supported by several brackets. The blower is then turned on, and fresh air from outside is sent into the underground water storage tank in conjunction with the air supply hose to replenish the oxygen inside the underground water storage tank and to assist in cooling the underground water storage tank, effectively improving the working environment inside the underground water storage tank.

[0008] Preferably, the bracket includes a support tube, the limiting member is located at the top of the support tube, and a support is vertically connected to the bottom of the support tube.

[0009] By adopting the above technical solution, the contact area between the support pipe and the ground is increased by using the support, so that the support can be more stably supported on the ground inside the water storage tank.

[0010] Preferably, a limiting pin is provided on the outer side of the top of the limiting member, and the limiting pin is used to block the top opening of the U-shaped limiting groove.

[0011] By adopting the above technical solution, after the air supply hose is embedded into the U-shaped limiting groove of the top limiting component of the bracket, the top opening of the U-shaped limiting groove is sealed by the limiting pin to prevent the air supply hose from coming out of the U-shaped limiting groove. This helps the air supply hose to be more stably supported by the bracket and lifted off the ground of the water storage tank.

[0012] Preferably, the bottom of the limiting member is connected to a support rod, which is coaxially inserted into the support tube; a limiting bolt is threaded through the outer circumference of the support tube, and the limiting bolt abuts against the support rod.

[0013] By adopting the above technical solution, the height of the limiting component can be adjusted, which makes it easy to flexibly adjust the height of the limiting component according to actual needs. This allows the limiting component to better lift the air supply hose off the ground of the water storage tank, thereby enabling the air supply component to deliver fresh air and cool the water storage tank and other enclosed spaces more stably and efficiently, and avoiding contact between the air supply hose and the ground, which would affect the air supply effect and service life.

[0014] Preferably, the outer periphery of the support tube is welded with a limiting tube, and the limiting tube is arranged perpendicularly to the support tube; the base is supported on both sides with limiting rods, the limiting rods are located above the base, and the limiting rods are used for the limiting tubes to be sleeved.

[0015] By adopting the above technical solution, when storing the device, the limiting tube on the outer periphery of the support tube can be inserted into the limiting rod above the base, so that the entire bracket can be stored on the base. This helps to limit the loss of the bracket while reducing the overall space occupied by the device.

[0016] Preferably, the base is vertically provided with a hose storage rod, which is used for winding the air supply hose.

[0017] By adopting the above technical solution, the air supply hose can be wound around the hose storage rod during storage, avoiding damage caused by random placement of the air supply hose. At the same time, it can reduce the space occupied and facilitate the overall storage and transportation of the device.

[0018] Preferably, a flexible buffer layer is laid on the inner side of the U-shaped limiting groove.

[0019] By adopting the above technical solution, the flexible buffer layer is used to restrict the rigid contact between the air supply hose and the limiting component, thus preventing relative movement between the air supply hose and the limiting component and causing wear of the air supply hose when the subsequent support or air supply hose is moved.

[0020] Preferably, the bottom of the support is equipped with several sets of casters.

[0021] By adopting the above technical solution, the bracket can be moved flexibly by several pairs of universal wheels at the bottom, making it easy to move the bracket to a designated position according to actual needs.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During the cleaning operation of the underground water storage tank, a blower and a hose are used to send fresh air from outside into the underground water storage tank to replenish the oxygen inside the tank and cool it down, effectively improving the working environment inside the underground water storage tank.

[0023] 2. By setting up several supports, the air supply hose can be lifted off the ground of the water storage tank to limit the air supply pipe from being soaked in sewage or trampled, which would affect the normal air supply of the air supply hose.

[0024] 3. By setting a limiting pin at the limiting rod at the top of the bracket, the air supply hose is embedded into the U-shaped limiting groove of the limiting component, and the limiting pin is used to seal the opening of the U-shaped limiting groove to prevent the air supply hose from detaching from the limiting component during subsequent use.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a fresh air cooling device for a closed space, referring to... Figure 1 and Figure 2 The system includes an air supply assembly and a support assembly. The air supply assembly includes a blower 1, with an air supply hose 11 connected to the blower 1's outlet. The support assembly includes several brackets 3, which are used to lift the air supply hose 11 off the ground. When cleaning enclosed spaces such as water storage tanks, the air supply hose 11 is moved into the water storage tank, and the brackets 3 lift the air supply hose 11 off the ground. The blower 1, in conjunction with the air supply hose 11, delivers fresh outside air into the water storage tank to replenish oxygen and cool it down.

[0031] Reference Figure 1 and Figure 2 The air supply assembly also includes a base 2, on which the blower 1 is mounted. Several main casters 21 are installed at the bottom of the base 2. The base 2 typically has a plate-like structure, formed by welding steel plates to a metal frame. The main casters 21 are installed at the bottom of the base 2 by bolts or welding. The base 2 facilitates the movement of the blower 1 during subsequent use. A push frame 22 is vertically welded to one end of the base 2, allowing operators to move the base 2 and the blower 1 using the push frame 22.

[0032] Reference Figure 1 and Figure 2 In this embodiment, the air supply hose 11 is a plastic hose, and the end of the air supply hose 11 is fixed to the air outlet of the blower 1 through a flange structure to achieve a stable connection between the air supply hose 11 and the blower 1.

[0033] Reference Figure 1 and Figure 2 The base 2 is vertically equipped with a hose storage rod 24, the bottom end of which is welded and fixed to the base 2. The hose storage rod 24 is used for winding the air supply hose 11. When the device is not in use, the air supply hose 11 can be wound around the hose storage rod 24 for easy storage and organization of the air supply hose 11.

[0034] Reference Figure 1 and Figure 2The bracket 3 includes a support tube 31, with a limiting member 32 at the top of the support tube 31. The limiting member 32 is made of steel plate; the limiting member 32 is bent to form a U-shaped limiting groove 320, which is used for embedding the air supply hose 11. When the air supply hose 11 is supported by the bracket 3, the air supply hose 11 can be embedded into the U-shaped limiting groove 320 of the limiting member 32, thereby lifting the air supply hose 11 off the ground and preventing the air supply hose 11 from being affected by sewage immersion or trampling. A limiting pin 321 is provided on the outer side of the top of the limiting member 32, extending into the U-shaped limiting groove 320 and sealing the top opening of the U-shaped limiting groove 320. The limiting pin 321 is specifically a metal pin. The air supply hose 11 located in the U-shaped limiting groove 320 is limited by the limiting pin 321 to prevent the air supply hose 11 from disengaging from the limiting member 32 during the subsequent movement of the bracket 3, which helps the air supply hose 11 to be more stably supported on the bracket 3.

[0035] Reference Figure 1 and Figure 2 A support 310 is provided at the bottom end of the support pipe 31, and the bottom end of the support pipe 31 is vertically welded to the support 310. This allows the support 310 to increase the contact area between the support pipe 31 and the ground, thereby increasing the stability of the bracket 3. Several sets of universal wheels 3101 are installed at the bottom of the support 310, which facilitates the flexible movement of the bracket 3 to a designated position according to actual needs.

[0036] Reference Figure 1 and Figure 2 A support rod 33 is vertically welded to the bottom of the limiting member 32, and the support rod 33 is coaxially inserted into the support tube 31. A limiting bolt 311 is threaded through the outer circumference of the top of the support tube 31, with one end of the limiting bolt 311 extending into the inner cavity of the support tube 31 and abutting against the outer side of the support rod 33. Through the above settings, the insertion depth of the support rod 33 in the support tube 31 can be flexibly adjusted, thereby adjusting the height of the limiting member 32 to meet different usage requirements.

[0037] Reference Figure 1 and Figure 2 A flexible buffer layer 322 is laid on the inner side of the U-shaped limiting groove 320. The flexible buffer layer 322 is made of rubber pad or sponge pad. The flexible buffer layer 322 enables flexible contact between the air supply hose 11 and the limiting member 32 to protect the air supply hose 11 and prevent wear when in contact with the limiting member 32.

[0038] Reference Figure 2 and Figure 3Each support tube 31 has a limiting tube 34 welded to its outer periphery. The limiting tube 34 is perpendicular to the support tube 31. Limiting rods 23 are provided on both sides of the base 2. The limiting rods 23 are horizontally positioned above the base 2. The two limiting rods 23 are welded to opposite sides of the push frame 22. The limiting rods 23 are used for the limiting tubes 34 to be fitted onto each other. When it is necessary to store the bracket 3, the limiting tubes 34 on the bracket 3 can be fitted onto the limiting rods 23 above the base 2 to achieve orderly storage of the bracket 3 and prevent the bracket 3 from being lost.

[0039] The implementation principle of this embodiment is as follows: When cleaning a confined space, the blower 1 is moved to the designated area via the base 2, and then the bracket 3 and the air supply hose 11 are moved into the confined space. After the bracket 3 is placed in position, the air supply hose is embedded into the U-shaped limiting groove 320 of the limiting member 32 at the top of each bracket 3, so that the air supply hose 11 is lifted off the ground of the confined space by the bracket 3. The blower 1 and the air supply hose 11 are used to send fresh air from the outside into the sealed space to replenish the oxygen in the confined space and cool the inside of the confined space.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
