Description

Technical Field

[0001] The present invention belongs to the technical field of secondary water supply systems, and in particular relates to a novel intelligent double-layer temperature-sensing integrated station building. Background Art

[0002] In the current field of secondary water supply, cabinets or station houses are common equipment installation cabinets, which are usually used for various types of water supply equipment and related water pumps and electronic components. The water supply equipment will generate a lot of heat and the alternation of temperature and humidity of the external environment during self-operation. Therefore, the station house needs to have the ability to dissipate heat and control temperature. For such station houses installed outdoors, not only heat dissipation but also moisture prevention needs to be considered. For example, in a rainy environment, the humidity in the air is very high. The heat dissipation method through air circulation can easily allow a large amount of water vapor to enter the cabinet, and condense into small water droplets inside the cabinet, which adhere to the electronic components inside. This can easily corrode the components, resulting in a short circuit in the internal circuit of the outdoor station house, resulting in a decrease in the life of the water supply equipment and the quality of operation. The technologies currently used in the industry are: adding a small air conditioner outside the cabinet; or building a small brick wall house next to the cabinet; or adding multiple small fans in the cabinet, but the above solutions have problems such as high noise, high cost expenditure, and poor structural stability.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a multifunctional room for an outdoor chiller in a pump station technology water supply system [202210256433.8], which includes a room body, the east and north sides of the room body are respectively a glass main structure, the south side is a fire-retardant rock wool board main structure, the west side is an electric roller shutter door main structure, and the roof is a herringbone resin roof structure, wherein the north and south sides are respectively provided with blinds and dustproof filters; the chiller includes a local control box and a water supply pipeline, the former is arranged near the west side of the room body and a maintenance door is provided on the side corresponding to the west side, and at least the north and south sides thereof are provided with air inlets and detachable grille air inlet plates matched therewith, the air inlets and blinds on the north and south sides of the local control box are connected in a line, and the top of the local control box is connected with an air outlet pipe and a cover.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1-9 As shown, a new type of intelligent double-layer temperature sensing integrated station room includes a cabinet 1, and the cabinet 1 is also connected to an inlet and outlet water pipe for connecting to an internal water supply unit 5. The water supply unit 5 generates heat during operation. The cabinet 1 is provided with an air inlet 11 at the lower end and an air outlet 12 at the upper end, and its internal air flow layout is bottom-in and top-out. A rain shelter 2 covering the air outlet 12 is installed on the top of the cabinet 1. The rain shelter 2 mainly prevents external rainwater from invading the interior of the cabinet 1. A fan assembly 3 is installed at the air outlet 12 on the top of the cabinet 1 to drive air flow. An air flow guide assembly 4 is provided between the fan assembly 3 and the rain shelter 2, and a flow limiting assembly 6 is provided between the fan assembly 3 and the cabinet 1. The air flow guide assembly 4 is mainly arranged inside the rain shelter 2 to guide the air to be discharged evenly, and the working noise of the fan assembly 3 when exhausting air is reduced by reducing the air flow rate.

[0034] Specifically, the rainproof ceiling 2 includes a horizontally arranged straight portion 21 and an inclined portion 22 bent upward relative to the straight portion 21. The inclined portion 22 of the rainproof ceiling 2 is opposite to the cabinet door at the front end of the cabinet 1, further preventing rainwater from invading the cabinet 1 along the gap of the cabinet door. A gap opposite to the exhaust hole 47 is left between the lower end of the rainproof ceiling 2 and the cabinet 1 for air to be discharged downward.

[0035] In depth, the airflow guide component 4 includes a guide cavity 41 arranged inside the rain shelter canopy 2, and the guide cavity 41 is vertically provided with a guide frame 42, and the guide frame 42 divides the guide cavity 41 into a front cavity 43 and a rear cavity 44, and the front cavity 43 and the rear cavity 44 are trapezoidal, wherein the rear cavity 44 is opposite to the inclined portion 22 of the rain shelter canopy 2. A triangular sub-cavity 45 is provided on both sides of the front cavity 43 and the rear cavity 44, and the air outlet 12 is connected to the front cavity 43; a through hole 46 is provided on the guide frame 42 to connect the front cavity 43 with the sub-cavity 45, and an exhaust hole 47 is provided at the lower end of the front cavity 43 and the sub-cavity 45, and the exhaust hole 47 is arranged adjacent to the edge of the rain shelter 2; the through hole 46 and the exhaust hole 47 are in a grid shape relative to the rain shelter 2; a guide blade 48 is provided in the front cavity 43 between the air outlet 12 and the exhaust hole 47, and the guide blade 48 is wavy, and guide channels 49 with different spacings are left between adjacent guide blades 48. Since the guide channel 49 is in a curved structure with the guide blade 48, the air is evenly guided to each exhaust hole 47 when it flows, and at the same time, the curved structure reduces the airflow resonance noise by reducing the high-intensity pressure wind speed.

[0036] The fan assembly 3 introduces the internal air of the cabinet 1 into the front cavity 43. Part of the air flows through the guide channel 49 and is evenly discharged from the exhaust holes 47 at the bottom of the front cavity 43. The other part of the air enters the sub-cavity 45 through the through holes 46 of the guide frame 42, and then is evenly discharged from the exhaust holes 47 at the bottom of the sub-cavity 45. The through holes 46 generate friction when the airflow passes through quickly to reduce its wind speed, thereby achieving uniform air flow.

[0037] Further, similar to the conventional feedback regulation structure, the fan assembly 3 in the present application includes a temperature-controlled fan 31 installed at the air outlet 12, the temperature-controlled fan 31 is connected to a fan controller, and the cabinet 1 is built with a temperature sensor connected to the fan controller. The temperature sensor monitors the internal temperature of the cabinet 1. If the temperature is too high, the power of the temperature-controlled fan 31 is increased to speed up the air flow. At the same time, the method of speeding up the air flow rate can also prevent water vapor condensation from corroding the internal components. The specific performance of the temperature-controlled fan 31 is as follows: Figure 7 shown.

[0038] Furthermore, the temperature control fan 31 includes a fan base 32, the fan base 32 has a built-in static impeller 33, a dynamic impeller 34 is rotatably mounted at the lower end of the static impeller 33, and a driving motor is installed between the static impeller 33 and the dynamic impeller 34. The temperature control fan 31 is based on the air volume, total pressure (= system resistance R + residual pressure loss h at the outlet of the whole machine c ), rotation speed and working medium (current air) density under main working conditions, calculate the "specific speed" to determine the type and pressure parameters of the temperature control fan 31. Here, the specific speed is between 120-200, so the temperature control fan 31 adopts an RS-level axial flow fan.

[0039] In addition, the fan base 32 has a diameter of 182 mm and a length of 72 mm, the impeller 34 has a diameter of 176 mm, the hub diameter of the impeller 34 is 97 mm, the impeller 34 blade tip clearance is 3 mm, the impeller 34 has 11 blades, and the stationary impeller 33 has 13 blades.

[0040] The impeller 34 in the temperature control fan 31 is designed using the equal annular volume method (or equal reaction degree method). Assuming that the axial velocity is constant, the velocity triangle at the inlet is drawn to confirm the inlet geometry angle and calculate the lift and density of the blades, which is used to confirm the number of blades, the size and blade type of different blade sections (selected according to parameters), and gradually calculate the outlet geometry angle of the blades. According to the inlet and outlet airflow angles of the impeller design, the static pressure increase in the impeller 34 is calculated, and the formula is:

[0041]

[0042] Among them, w1 and w2 are the relative speeds of the moving blade inlet and outlet, and ρ is the working fluid density.

[0043] When designing the stationary impeller 33 in the temperature control fan 31, the outlet airflow triangle of the moving blade is first drawn, and the absolute velocity and absolute airflow angle of the moving blade outlet are used as the inlet airflow velocity and airflow angle of the stationary blade, and the static pressure required to be increased by the stationary blade is calculated. The formula is:

[0044] P2 = R - P1;

[0045] As for the stationary blades, since they do not do work on the airflow, without considering the flow channel loss, the increase in static pressure = the decrease in dynamic pressure. The dynamic pressures in the axial direction of the inlet and outlet airflow are equal, so it is only necessary to calculate the radial dynamic pressure difference = P2 to calculate the radial velocity C at the outlet. 2u , and the known condition that the axial velocity is constant, the outlet airflow angle g2 of the stator blade can be calculated, which can be used as the outlet geometric angle β of the stator blade 2d , or select a 0-5° backward angle appropriately based on design experience, the relationship is: airflow backward angle δ = β 2A -β2, and then calculate the number of blades of the stationary blades, as well as the size and blade shape of each section according to the same design steps as the moving blades.

[0046] Meanwhile, the cabinet 1 includes an outer shell 13 and an inner shell 14, with a thermal insulation layer between the outer shell 13 and the inner shell 14; the front and rear ends of the cabinet 1 are respectively closed by double-layer door panels 15 with built-in thermal insulation layers, and an elastic sealing strip is provided at the junction of the cabinet 1 and the double-layer door panels 15. The cabinet 1 is made of double metal material as a whole, and the internal thermal insulation layer is used to block the external radiation temperature. When the front and rear of the cabinet 1 are completely closed, only the fan assembly 3 and the airflow guide assembly 4 use convection to perform heat exchange.

[0047] It can be seen that a multi-layer filter 17 is installed at the air inlet 11 at the lower end of the cabinet 1 to prevent dust and other external impurities from invading the interior of the cabinet 1. A support frame 18 is provided at the bottom of the cabinet 1 and is located above the air inlet 11. A support plate 19 is fixed to the upper end of the support frame 18. A cavity for air flow is left between the support frame 18 and the support plate 19 to ensure that air rises from the cabinet 1 and flows through the water supply unit 5. The support plate 19 is provided with grille-shaped air guide holes 16 to realize air diversion.

[0048] Obviously, the cabinet 1 has a built-in water supply unit 5, which is connected to the Internet of Things and the central detection platform. The Internet of Things is used to realize remote monitoring of the water supply unit 5. At the same time, the Internet of Things is connected to the sensor elements inside the cabinet 1 to upload fault information and abnormal status in time to ensure the efficiency of station management.

[0049] Preferably, the control algorithm of the fan assembly 3 load and the internal temperature of the cabinet 1 is as follows:

[0050]

[0051] Wherein, T is the internal temperature of the cabinet 1, and N is the fan load. The fan assembly 3 has different gears to adapt to different temperatures, and maintains the internal temperature of the cabinet 1 within a specified range through negative feedback regulation.

[0052] In addition, in order to further improve the sealing of the top of the cabinet 1 without affecting the normal exhaust, the current limiting component 6 includes a current limiting disc body 7 installed on the top of the cabinet 1, and the current limiting disc body 7 has a built-in flap component 8, and a linkage opening and closing component 9 is arranged between the flap component 8 and the fan component 3. The linkage opening and closing component 9 provides a driving torque for the flap component 8, and the movement of the flap component 8 adjusts the air intake volume and air intake position of the fan component 3 accordingly. The air duct inside the cabinet 1 is adjusted to adjust the air flow direction accordingly to ensure sufficient heat exchange.

[0053] At the same time, unlike the conventional opening and closing structure, the flow limiting disc body 7 in this embodiment includes an upper disc body 71 and a lower disc body 72, and a flow limiting cavity 73 is left between the upper disc body 71 and the lower disc body 72. The upper disc body 71 is fitted with the cabinet 1 and a flow limiting hole 74 opposite to the fan assembly 3 is opened in the middle. The lower disc body 72 is provided with air inlet slots 75 arranged in a central symmetrical manner. The air inlet slots 75 are arranged in a concentric circle shape relative to the lower disc body 72 and are divided into a first air inlet slot, a second air inlet slot and a third air inlet slot from the inside to the outside. The radial lengths of the first air inlet slot, the second air inlet slot and the third air inlet slot are consistent and the widths gradually decrease; the flap assembly The component 8 includes a concentric ring-shaped flip ring 81 which is rotatably installed in the flow limiting cavity 73. A flip plate 82 which is arranged symmetrically and opposite to the air inlet slot 75 is hinged between the flip rings 81. The flip plates 82 in the same circumferential direction are mutually attached or separated as the flip rings 81 rotate. A flip slide 83 and a flip slide bar 84 which are mutually slidably connected are arranged between the upper plate 71 and the lower plate 72 and the flip ring 81. The flip plate 82 includes a main flap 85 hinged to the flip ring 81 and a secondary flap 86 which is telescopically connected to the main flap 85. The other end of the secondary flap 86 is hinged to another flip ring 81. Each flip ring 81 rotates independently to adjust the circumferential direction and radial inclination angle of each flip plate 82. The flip plate 82 can overlap or separate with the air inlet slot 75 to achieve complete closure or opening, or can cross with the air inlet slot 75 to further adjust the radial direction and air intake volume of the air inlet.

[0054] Furthermore, the linkage opening and closing assembly 9 stops synchronously with the fan assembly 3, and includes a linkage gear ring 91 arranged on the flip ring 81, the linkage gear ring 91 is respectively meshed with a linkage gear 92, the linkage gear 92 is respectively connected to an independently controlled linkage motor 93, and a relay is arranged between the linkage motor 93 and the fan assembly 3. The linkage motor 93 is started to drive the linkage gear ring 91 and the linkage gear 92 to mesh and transmit, and each flip ring 81 rotates independently, thereby realizing the synchronous adjustment of the flip plate 82 in the same circumferential direction.

[0055] To sum up, the principle of this embodiment is that the fan assembly 3 on the top of the cabinet 1 provides driving force, driving the air inside the cabinet 1 to flow from bottom to top through the water supply unit 5, and then is evenly guided by the airflow guide assembly 4 to the edge of the rainproof ceiling 2 for output, wherein the airflow guide assembly 4 effectively reduces the air flow noise.
