Description

Technical Field

[0001] The present invention relates to the technical field of dust removal and water removal equipment, and in particular to a dust removal and water removal device for an outdoor chassis. Background Art

[0002] As the number of outdoor electronic devices increases and their performance becomes higher and higher, the heat power consumption also increases. Even more electronic devices are required to be installed in the same chassis. Therefore, the heat dissipation requirements for outdoor chassis are also increasing, and even fans must be used for heat dissipation.

[0003] Currently, active ventilation and cooling for outdoor computer chassis typically involves installing one or more air inlets and outlets. Fans then draw cool air from outside the chassis into the chassis, while simultaneously exhausting hot air from the inside to achieve effective cooling. However, preventing dust from entering the chassis in dusty environments is a common practice. Adding filters to the air inlets is a common method for filtering out dust. However, these filters clog over time, resulting in poor cooling performance. Frequent filter replacement is also prohibitively troublesome, making this impossible in dusty environments.

[0004] In some cases, the air intake of the chassis may be mixed with water droplets. These water droplets entering the chassis may cause damage to electronic equipment and result in economic losses. Summary of the Invention

[0005] 1. Technical problem to be solved by the invention

[0006] The object of the present invention is to provide an outdoor chassis dust and water removal device, which can realize continuous and effective dust and water removal in dusty environments and solve the problem of excessive dust clogging the filter.

[0007] 2. Technical solution

[0008] In order to solve the above problems, the technical solution provided by the present invention is:

[0009] A dust and water removal device for an outdoor chassis, comprising an air intake assembly, a dust collecting barrel, and a dust collecting blade assembly, the dust collecting barrel comprising an inner barrel and an outer barrel, the inner barrel having an air intake channel, a dust collecting chamber between the inner barrel and the outer barrel, the dust collecting blade assembly being arranged in the air intake channel and comprising a main shaft, coaxially arranged with the dust collecting barrel; a plurality of blades being arranged circumferentially along the main shaft and a plurality of groups being provided axially along the main shaft; the blades being a V-shaped structure with an opening toward the air intake end of the air intake channel, and ribs being provided on both sides of the blades; a driving member for controlling the rotation of the main shaft; an angle between the ribs and the blades being no greater than 90°, a plurality of annular grooves being provided on the inner barrel along its axial direction, and the blades extending through the annular grooves into the dust collecting chamber.

[0010] Preferably, several blades in the same group are connected by reinforcing ribs.

[0011] Preferably, the reinforcing rib is an annular structure and is arranged at the annular groove.

[0012] Preferably, a plurality of annular shielding edges are provided in the dust collecting chamber, and the shielding edges are provided between two adjacent annular grooves. The outer diameter of the shielding edges is larger than the outer diameter of the blades and smaller than the inner diameter of the outer cylinder.

[0013] Preferably, an upper baffle is spaced apart above the inner end of the shielding edge.

[0014] Preferably, the outer end of the blade is provided with a guide slope arranged obliquely downward.

[0015] Preferably, a water storage cavity is provided inside the main shaft, and a plurality of water outlet holes corresponding to the plurality of blades are provided on the main shaft, and a pressure one-way valve is provided at the water outlet holes.

[0016] Preferably, the opening pressure of the pressure one-way valve near the air inlet end of the air inlet passage is smaller than the opening pressure of the pressure one-way valve near the air outlet end of the air inlet passage.

[0017] Preferably, it also includes a cooling system for controlling the water temperature in the water storage chamber.

[0018] Preferably, a water storage cavity is provided inside the main shaft, and a plurality of water outlet holes corresponding to the plurality of blades are provided on the main shaft, and an electric control valve is provided at the water outlet hole.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0021] 1) The dust and water removal blade structure of this invention effectively captures dust particles and water droplets in the airflow, centrifugally collecting them in the annular dust collection canister. A filter uses a fine mesh to trap dust particles, so its mesh size determines its blocking effect and ventilation efficiency. To address this issue, this solution abandons the filter and instead uses blades with a specifically designed structure to capture dust particles and water droplets and promptly transport them to the dust collection canister, eliminating the problem of dust accumulation leading to clogging.

[0022] 2) To enhance dust removal effectiveness in particularly dusty environments, this invention incorporates a water-spraying dust capture mechanism, allowing scattered dust particles to quickly aggregate into larger particles and collect in the dust collection bin. The water outlet is normally closed and only opens when the water pump is operating, opening the outlet to spray water. Furthermore, the water pressure at each layer of dust-collecting blades varies, ensuring that the lower-level outlets are more likely to be used, thus conserving water.

[0023] 3) In order to solve the condensation problem caused by sudden changes in external temperature when an outdoor chassis may operate in a high-humidity environment, the present invention does not add any additional structure to the original dust removal mechanism so that it has the function of condensing and removing water vapor, making its air intake system function more complete and solving many pain points encountered in the current industry.

[0024] 4) The dust and water removal equipment of the present invention has a simple structure, is easy to manufacture, and can be installed as an accessory on various outdoor chassis, and has a good market prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0034] Combined with attachment Figures 1-4, an outdoor chassis dust and water removal device of the present embodiment includes an air intake assembly 1, a dust collecting barrel 2, and a dust collecting blade assembly 3. In the present embodiment, the state of the dust collecting barrel 2 being axially vertical is taken as an example for explanation. The air intake assembly 1 is fixed to the upper end of the dust collecting barrel 2, so that the gas passes through the dust collecting barrel 2 from bottom to top. The dust collecting barrel 2 includes an inner cylinder 21 and an outer cylinder 22 fixedly connected. The inner cylinder 21 and the outer cylinder 22 are two cylinders with coaxial centers but different diameters. The diameter of the outer cylinder 22 is larger than the diameter of the inner cylinder 21. The inner cylinder 21 is hollow inside to form an air intake channel 2a. The dust collecting chamber 2b is formed between the inner cylinder 21 and the outer cylinder 22 due to the size difference. The dust collecting blade assembly 3 is arranged in the air intake channel 2a and includes a main shaft 31, which is coaxially arranged with the dust collecting barrel 2. The main shaft 31 is arranged at the axis of the dust collecting barrel 2; a plurality of blades 32 are arranged circumferentially along the main shaft 31 and a plurality of groups are provided axially along the main shaft 31, each group including at least two or more blades 32 and are radially distributed, each group of blades 32 are staggered at a certain angle, and after multiple groups are superimposed, the air inlet channel 2a of the dust collecting barrel 2 is basically blocked by multiple groups of blades 32 when viewed from top to bottom; the blades 32 are a V-shaped structure with an opening toward the air inlet end of the air inlet channel 2a (downward in this embodiment), the cross-section of the blades 32 is a large obtuse angle, and ribs 33 are provided on both sides of the blades 32. The ribs 33 are provided on the lower surface of the blades 32 and are the same length as the blades 32. The angle between the ribs 33 and the blades 32 is not greater than 90° (an acute angle); a driving member 34 is used to control the rotation of the main shaft 31. In this embodiment, the driving member 34 is a motor and is mounted on the upper end of the dust collecting barrel 2; a plurality of annular grooves 2c are provided on the inner cylinder 21 along its axial direction, and each group of blades 32 corresponds to an annular groove 2c. The blades 32 pass through the annular groove 2c and extend into the dust collecting chamber 2b, that is, the diameter of the same group of blades 32 is larger than the diameter of the inner cylinder 21.

[0035] The working principle of the blades 32 collecting dust and water droplets in the intake air flow is as follows: Under the action of the intake assembly 1, an upward intake air flow is generated in the intake channel 2a. When the intake air flow encounters the blades 32 in the upward flow, it forms a V-shaped structure under the guidance of the blades 32. Figure 4 As shown in the intake air flow trajectory, during the flow process, because the mass of dust particles and water droplets is relatively large, the dust particles and water droplets will move along the dust trajectory of the marked line under the action of inertia. While the blades 32 rotate, the dust particles and water droplets will be guided by the V-shaped structure and gathered at the rib 33 at the edge of the V-shaped structure. Due to the centrifugal effect, the dust particles and water droplets are thrown radially outward along the main shaft 31. The dust particles and water droplets are finally collected in the dust collecting chamber 2b. It is sufficient to clean the dust collecting chamber 2b regularly, and an outlet can also be set to continuously discharge through a pipe.

[0036] This outdoor chassis dust and moisture removal device achieves continuous and effective dust removal during air intake in dusty environments, solving the problem of excessive dust clogging the filter; it removes moisture during air intake to prevent water from entering at the same time as air intake; the overall structure has no parts that require frequent maintenance, with low maintenance costs, making it suitable for large-scale deployment.

[0037] As a preferred solution of the present invention, in order to improve the connection strength and stability during rotation between the blades 32 in the same group, several blades 32 in the same group are connected by reinforcing ribs 4, and the reinforcing ribs 4 are designed to be annular and arranged at the annular groove 2c. The diameter of the reinforcing ribs 4 is consistent with the diameter of the inner cylinder 21, and the height of the reinforcing ribs 4 is close to the height of the annular groove 2c. This design mainly serves to prevent internal dust from returning to the air intake channel 2a.

[0038] As a preferred embodiment of the present invention, a plurality of annular shielding edges 5 are provided in the dust collecting chamber 2b. The outer ends of the shielding edges 5 are tilted downward to form a slope. The shielding edges 5 are provided between two adjacent annular grooves 2c. The outer diameter of the shielding edge 5 is larger than the outer diameter of the blade 32 and smaller than the inner diameter of the outer tube 22. The outer end of the shielding edge 5 and the inner wall of the outer tube 22 are spaced to form a channel allowing dust and water droplets to fall downward. Moreover, since the outer diameter of the shielding edge 5 is larger than the outer diameter of the blade 32, the dust and water droplets falling downward can be effectively prevented from falling on the blade 32 below and causing secondary rebound.

[0039] As a preferred embodiment of the present invention, an upper baffle 6 is provided above the inner end of the shielding edge 5, and the upper baffle 6 is horizontally provided at the lower edge of the upper annular groove 2c, and the outer end of the blade 32 is provided with a guide slope 7 arranged obliquely downward. The setting of the guide slope 7 changes the rebound angle of dust and water droplets after hitting the inner wall of the outer cylinder 22, such as Figure 3 As described above, after the dust and water droplets hit the inner wall of the outer cylinder 22, they first bounce back to the inner wall of the outer cylinder 22, then bounce back to the shielding edge 5, and then bounce back to the upper baffle 6. Finally, after multiple bounces between the upper baffle 6 and the shielding edge 5, they fall on the upper surface of the shielding edge 5 and slide along its surface. This design can effectively release the centrifugal force of dust and water droplets, and prevent them from rebounding back into the air intake channel 2a.

[0040] As a preferred embodiment of the present invention, the main shaft 31 has a water storage chamber 8 inside, and also includes a water tank and a water pump for replenishing water to the main shaft 31. The main shaft 31 is provided with a number of water outlets 9 arranged one-to-one corresponding to the number of blades 32. The water outlet 9 is provided with a pressure one-way valve, such as a rubber valve sheet that automatically opens under a large pressure. The pressure one-way valve requires a certain force to be pushed open. The water thrown out by centrifugal force flushes the V-shaped groove of the blade 32, which can ensure the smoothness of the inner surface of the blade 32 and ensure that the route of dust and water droplets when being thrown out is stable. The pressure of the pressure one-way valve on the water outlet 9 increases from the lower dust collecting blade 32 to the upper layer. This is because the dust particles contained in the intake air flow will be smaller as you go up, which greatly saves water and improves overall efficiency.

[0041] As a preferred embodiment of the present invention, to specifically remove water vapor from the high-humidity intake airflow, a cooling system is also included for controlling the water temperature within the water storage chamber 8. Specifically, an internal temperature and humidity sensor is located above the intake assembly 1, and an intake temperature and humidity sensor is located below the dust collecting blade assembly 3. A heat exchange block supported by a highly thermally conductive metal (aluminum or copper) is installed within the water tank supplying water to the spindle 31. The heat exchange block is connected to a semiconductor heat sink, and the water tank also contains a temperature sensor. These components, combined with the semiconductor heat sink control circuit, form a cooling system that cools the water within the water tank. The dust collecting blade assembly 3 is made of a highly thermally conductive metal (aluminum or copper). When the intake temperature and humidity sensor detects high humidity in the intake air, the cooling system activates, lowering the water tank temperature. This lowers the temperature of the dust collecting blade assembly 3, causing water vapor in the intake airflow to condense on the lower surface of the blades 32 and subsequently be drawn into the dust collecting barrel 2. The water temperature is adjusted by comparing the humidity changes detected by the intake temperature and humidity sensor with the internal temperature and humidity sensor. Of course, the water temperature must be set to prevent freezing.

[0042] As another preferred embodiment of the present invention, in order to remove dust more effectively, an internal dust detection sensor is provided above the air intake assembly 1, and an air intake dust detection sensor is provided below the dust collecting blade assembly 3. A water storage chamber 8 is provided inside the main shaft 31, and a plurality of water outlets 9 corresponding to the plurality of blades 32 are provided on the main shaft 31. An electric control valve is provided at the water outlet 9. The main shaft 31 is connected to the water pump tank so that the water outlet 9 can spray water under program control. In an environment with particularly high dust content, when the internal dust detection sensor detects that the dust content in the air is still very high, in order to better capture dust particles, the water outlet 9 can be controlled to spray water so that the dust particles in the air intake are moistened to make them easier to capture. In addition, the data of the internal dust detection sensor and the air intake dust detection sensor can be transmitted through the network of devices inside the chassis, and the numerical relationship between them can also be used to analyze whether the dust removal mechanism has failed.

[0043] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
