[0034] Deep mines are severely affected by high-temperature heat damage all year round, resulting in a significant reduction in production efficiency and a significant increase in accident rates. The treatment is urgent. The mine-use combined cabinet drives the fan to rotate through water power, and uses the water resources in the mine and the air in the mine for water-air heat exchange to provide cold air. In order to make full use of the water resources in the mine and increase the heat exchange amount, the current mine-use combined cabinet adopts a structure with two hydraulic fans connected in series. The two hydraulic fans are arranged at both ends of the frame, and a surface cooler is also arranged on the frame. Among them, the two hydraulic fans are connected in series through a connecting water pipe. After the water source enters the hydraulic fan through the water inlet of one of the hydraulic fans, it then flows out of the water outlet of the hydraulic fan and enters the connecting water pipe. The water in the connecting water pipe then enters the other hydraulic fan through the water inlet of the other hydraulic fan and flows out from the water outlet. However, it is designed for the ventilation roadway below the mine and cannot be applied to small areas such as underground chambers, substations, and operation posts in coal mines, resulting in the problem that such small areas with small spaces still have the problem of continuous high temperature and high humidity, causing a reduction in production efficiency and an increase in accident rates. For this reason, the present application provides a Figures 1 to 5The shown hydraulic fan includes: a hydraulic housing 1; a wind power housing 2, which is located on one side of the hydraulic housing 1, and an air inlet and an air outlet are provided on the wind power housing 2; a power component 3, which is arranged in the hydraulic housing 1, and the water entering the hydraulic housing 1 can drive the power component 3; at least two groups of blade assemblies, all the blade assemblies are arranged in parallel in the housing along the direction from the air inlet to the air outlet, and all the blade assemblies are connected to the power component 3. By arranging at least two blade assemblies in the wind power housing 2, the air volume can be increased on the premise of minimizing the wind power housing 2 as much as possible, reducing the overall volume of the hydraulic fan, and facilitating its application in mine areas with small space dimensions. It overcomes the problem that the mine use combined cabinets designed for mine roadways in the prior art cannot be applied, realizes the purpose of air supply and cooling in areas such as underground chambers, substations, and operation posts with small space dimensions, effectively improves production efficiency, and reduces the accident rate. Moreover, increasing the number of blade assemblies can relatively reduce the diameter of the blade assemblies, further reducing the diameter size of the wind power housing 2 and the overall volume of the hydraulic fan; at the same time, due to the increase in the number of blade assemblies, the rotation speed of each blade assembly is reduced, thereby reducing the wear on the corresponding bearings of the blade assemblies and improving the operating stability of the hydraulic fan. The power component 3 can receive water flow to obtain energy and can use this energy to drive the blade assemblies to rotate, realizing non-electric drive and no explosion possibility, ensuring the reliable operation of the hydraulic fan.

[0035] As Figure 1 shown, the number of blade assemblies is two. Compared with the hydraulic fan with only one blade assembly, the air volume of this hydraulic fan is increased from 757 m 3 / h to 470 m 3 / h, the rotation speed of the blade assemblies is reduced from 3163 rpm to 2735 rpm, and the overall efficiency of the hydraulic fan is increased from 2.09% to 3.73%.

[0036] Among them, the blade assembly includes a blade 41 and a guide vane 42. The guide vane 42 is arranged in the wind power housing 2, and the blade 41 is rotatably arranged in the wind power housing 2. The rotation of the blade 41 can drive the gas to flow, and the arrangement of the guide vane 42 can adjust the static pressure of the gas, thereby ensuring the driving effect of the blade assembly on the gas.

[0037] All the blades 41 are coaxially arranged on a drive shaft, and the drive shaft is connected to the power component 3. Using the same drive shaft to drive all the blades 41 to rotate simultaneously ensures the reliable rotation of the blades 41 and also ensures the synchronous operation of all the blades 41, avoiding the situation where some blades 41 do not rotate and affecting gas flow, and ensuring the reliable operation of the hydraulic fan.

[0038] Along the axial direction of the drive shaft, the minimum distance between the wind blade 41 and the guide vane 42 ranges from 4 ± 1 mm. By setting the minimum distance, it is possible to avoid structural interference between the wind blade 41 and the guide vane 42 during the rotation of the wind blade 41, ensuring the reliable rotation of the wind blade 41 and the reliable operation of the hydraulic fan.

[0039] The minimum distance between the wind blade 41 and the wind power housing 2 ranges from 4 ± 1 mm. By setting the minimum distance, it is possible to avoid structural interference between the wind blade 41 and the wind power housing 2 during the rotation of the wind blade 41, ensuring the reliable rotation of the wind blade 41 and the reliable operation of the hydraulic fan.

[0040] In a wind blade assembly, the guide vane 42 can obstruct the air flow generated by the wind blade 41 to increase the static pressure of the air flow. Therefore, along the direction of air flow, the wind blade 41 and the guide vane 42 are arranged in sequence. The wind blade 41 is used to drive the gas, and the guide vane 42 is used to increase the static pressure of the air flow. However, multiple wind blade assemblies will cause the static pressure of the air flow to be too high, resulting in the problem of unsmooth air outlet. To ensure the air outlet effect of the hydraulic fan, along the air flow direction in the wind power housing 2, the inclination angles of the guide vanes 42 in all the wind blade assemblies gradually increase. By gradually increasing the inclination angle, the ability of the guide vane 42 to generate static pressure is reduced, thereby ensuring that the hydraulic fan can smoothly discharge air and ensuring the reliable operation of the hydraulic fan.

[0041] As Figure 1 shown, the number of wind blade assemblies is two. The wind blade 41 in the first wind blade assembly rotates to suck the air flow into the wind power housing 2, and the guide vane 42 increases the static pressure of the air flow and flows to the second wind blade assembly. The wind blade 41 in the second wind blade assembly rotates to continue driving the air flow, and its guide vane 42 equalizes the air flow. That is, the inclination angle of the guide vane 42 in the first wind blade assembly is smaller and can pressurize the air, and the inclination angle of the guide vane 42 in the second wind blade assembly is larger and can smoothly discharge air, thereby achieving the effect of a larger air volume at the same rotational speed.

[0042] Among them, the inclination angle of the guide vane 42 refers to the inclination angle of the guide vane 42 relative to the radius it corresponds to, which is the angle between the tangent of the outer edge of the guide vane 42 and the radius corresponding to the outer edge of the guide vane 42. The larger the angle, the larger the inclination angle of the guide vane 42, indicating that the inclination degree of the guide vane 42 is larger and the obstruction effect of the guide vane 42 on the air flow is smaller.

[0043] An inflow channel 11 is provided on the hydraulic housing 1. One end of the inflow channel 11 forms a water inlet on the hydraulic housing 1. Along the water inlet to the power component 3, the flow area of the inflow channel 11 gradually decreases. By gradually reducing the flow area of the inflow channel 11, the flow velocity of the water entering the hydraulic housing 1 is increased, thereby increasing the rotational speed of the power component 3 and further improving the working efficiency of the hydraulic fan.

[0044] An air-conditioning component needs to be installed underground in a mine. Cooling water will be sent into the air-conditioning component through a cooling water pipeline to achieve refrigeration. In order to reduce the structural complexity underground in the mine, the inflow channel 11 is provided with a water inlet on the hydraulic housing 1, and the water inlet is communicated with the cooling water pipeline. The cooling water in the cooling water pipeline enters the inflow channel 11 through the water inlet and flows along the inflow channel 11 to drive the rotation of the power component 3 at the power component 3, thereby achieving the purpose of driving the impeller 41 to rotate to drive the gas to flow. Since the cooling water only drives the power component 3 to rotate, it will not generate a large temperature rise, and the cooling water that causes the power component 3 to complete rotation can flow out of the hydraulic housing 1 and continue to flow to the downstream structure, and still be able to maintain the refrigeration effect of the cooling water.

[0045] The power component 3 includes an impeller, and the outflow direction of the inflow channel 11 faces the impeller, so that the water flow in the inflow channel 11 can drive the impeller to rotate. The impeller is arranged on the rotating shaft, and the rotation of the impeller can be transmitted to the impeller 41 through the rotation of the rotating shaft, thereby realizing the driving of the gas by the hydraulic fan.

[0046] The hydraulic fan further includes a base 5, the wind power housing 2 is arranged on the base 5, and a strengthening structure 6 is arranged between the wind power housing 2 and the base 5 to increase the structural strength of the hydraulic fan by using the strengthening structure 6 and improve the structural reliability of the hydraulic fan.

[0047] The wind power housing 2 includes an upper housing and a lower housing. The lower housing is fixedly arranged on the base 5, and the upper housing is detachably arranged on the lower housing. By arranging the upper housing and the lower housing, it is convenient to disassemble and assemble the wind power housing 2, and the end of the strengthening structure 6 is located at the connection position between the upper housing and the lower housing. The connection strength between the upper housing and the lower housing is further increased by using the end of the strengthening structure 6, and the reliability of the wind power housing 2 is improved.

[0048] A fan coil unit includes the above-mentioned hydraulic fan. The fan coil unit includes a heat exchange coil, and the air outlet of the hydraulic fan faces the heat exchange coil, so as to be able to drive the air flow to blow towards the heat exchange coil and improve the heat exchange efficiency of the heat exchange coil.

[0049] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
