DETAILED DESCRIPTION

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Embodiment 1: An intelligently controlled electromechanical equipment cooling protection device, referring to Figure 1-Figure 3 As shown, it includes: a protection box body 1, which is equipped with a fixed shell 11 and a control terminal, and the fixed shell 11 is used to carry electromechanical equipment; a temperature sensor 12, which is installed in the fixed shell 11; a fixed shell 13, which is fixedly connected to the protection box body 1, and is provided with an air duct 14, and the air duct 14 is connected to the fixed shell 11; an air duct 15, which is arranged in the fixed shell 13, and a filter is installed on the right side of the air duct 15, and an electric fan 16 is installed in the air duct 15, and the temperature sensor 12 is electrically connected to the electric fan 16, so as to adjust the power of the electric fan 16 by using the temperature in the fixed shell 11; an exhaust pipe 17, which is fixedly connected and connected to the fixed shell 11, and the exhaust pipe 17 penetrates the protection box body 1 and is fixedly connected thereto; a monitoring mechanism, which is arranged in the fixed shell 11, and is used to monitor whether the temperature in the fixed shell 11 continues to rise.

[0022] In the above scheme, a sealed door is provided on the front side of the protection box body 1, and eight elastic support blocks are provided in the fixed shell 11. The elastic support blocks in the fixed shell 11 are used to support the electromechanical equipment, and the elasticity of the support blocks is used to reduce vibration and noise and buffer accidental impacts. The control terminal is electrically connected to all electrical components in the device. The filter on the air duct 15 is used to filter dust impurities in the air to prevent dust from adhering to the electromechanical equipment in the fixed shell 11 and affecting its heat dissipation. If the electromechanical equipment placed in the fixed shell 11 needs to be protected in all directions, a nozzle and a liquid storage tank for spraying coolant are provided on the fixed shell 11, and a solenoid valve electrically connected to the control terminal is installed on the nozzle. When the temperature sensor 12 detects that the temperature of the electromechanical equipment is too high, the emergency processing mode is started, and the control terminal controls the solenoid valve to open, so that the coolant is sprayed on the electromechanical equipment for water cooling.

[0023] Reference Figure 2-Figure 4 As shown, the exhaust pipe 17 is fixedly connected to and communicated with the conduit 1 2 , the upper part of the conduit 1 2 is sleeved on the outside of the air guide pipe 2 15 , the conduit 1 2 is fixedly connected to and communicated with the conduit 2 21 , and the conduit 21 is wound around the outside of the fixed shell 2 13 .

[0024] In the above scheme, the fixed shell 13 is approximately T-shaped, the conduit 21 has a section in a spiral shape, and the spiral portion of the conduit 21 is wound around the right part of the fixed shell 13. The spiral portion of the conduit 21 and the right part of the fixed shell 13 are both made of heat-conducting materials, which are used to transfer the exhaust gas temperature in the conduit 21 to the fixed shell 13 and dry the flowing gas in the fixed shell 13. It can effectively reduce the energy effect and prevent moisture from corroding electromechanical equipment, thereby extending the service life of the electromechanical equipment.

[0025] Reference Figure 3 and Figure 5 As shown, the monitoring mechanism includes: a fixed shell three 3, fixedly connected to the fixed shell one 11; a sliding plug 31, slidably arranged in the fixed shell three 3, and forming a chamber filled with medium with the fixed shell three 3, and the expansion amount of the medium between the sliding plug 31 and the fixed shell changes linearly with the temperature; a pressure sensor 32, installed in the fixed shell three 3, the pressure sensor 32 is used to detect the position of the sliding plug 31, an electric part for changing the direction of airflow is installed in the air guide tube one 14, and the electric part on the air guide tube one 14 is electrically connected to the temperature sensor 12; the sliding plug 31 is installed with a rubber ring, and the closer the rubber ring on the sliding plug 31 is to the pressure sensor 32, the larger its inner diameter is, and the rubber ring of the sliding plug 31 is in contact with the fixed shell three 3.

[0026] In the above scheme, the electric parts on the air duct 14 form a shutter at its lower part, the fixed shell 3 3 is made of heat-conducting material, and the left part of the fixed shell 3 3 is provided with a through hole, the rubber ring on the sliding plug 31 is made of high-temperature resistant material, and the medium in the chamber formed by the fixed shell 3 3 and the sliding plug 31 is an alcohol-like medium with a large volume expansion coefficient. When the pressure sensor 32 is triggered, the temperature sensor 12 will feed back the monitored temperature to the control terminal, and the control terminal will subsequently adjust the power of the electric fan 16 accordingly, that is, adjust the heat dissipation efficiency, so that the electromechanical equipment is in a suitable temperature environment. During this process, the pressure sensor 32 does not work, and the control terminal does not adjust the power of the electric fan 16 according to the temperature change of the temperature sensor 12, so as to prevent the electromechanical equipment from adjusting the power of the electric fan 16 under a short-term load increase state (the load increase at this time will not exceed the rated load of the electromechanical equipment too much), thereby avoiding frequent adjustment of the working frequency of the electric fan 16, saving energy while ensuring the safe working state of the electromechanical equipment, that is, reducing the overall energy consumption of the cooling protection device, and saving costs.

[0027] Specific working principle: when using this device to perform cooling protection on designated electromechanical equipment, the electric fan 16 is started through the control terminal to work, and the electric fan 16 guides the external air through the air duct 2 15, the fixed shell 2 13 and the air duct 1 14 into the fixed shell 1 11, and then the flowing gas blows the electromechanical equipment, and the gas absorbs the heat on the electromechanical equipment to complete the cooling protection of the electromechanical equipment, and the gas after subsequent heat absorption is discharged to the outside through the exhaust pipe 17, the conduit 1 2 and the conduit 2 21.

[0028] In the process of cooling the electromechanical equipment by gas circulation, when the load of the electromechanical equipment fluctuates briefly, the load of the electromechanical equipment increases, causing its heat generation to increase, that is, the temperature in the fixed shell 11 gradually increases, and the gas with increased temperature transfers the heat to the medium therein through the fixed shell 3 3, and the medium therein expands due to the temperature increase, and the expanded medium squeezes the sliding plug 31 to move forward, and the sliding plug 31 is hindered by the rubber ring thereon, and the sliding plug 31 moves forward slowly. During this process, the temperature sensor 12 detects the temperature increase, and the temperature sensor 12 starts the rotation of the electric part on the air guide pipe 14 through the control terminal, changes the angle of the exhaust port on the air guide pipe 14, and makes the gas form a rotation trend in the fixed shell 11, and the rotation of the gas causes the gas temperature to be stratified according to the "thermal centrifugal effect", wherein the high-temperature gas gathers near the inner wall of the fixed shell 11, and the gas temperature near the electrical equipment is relatively low, which is convenient for the gas to carry more heat, so that the electrical equipment is always at a suitable temperature to work.

[0029] When the sliding plug 31 does not move to the extrusion pressure sensor 32 and the load of the electromechanical equipment is restored, under the continuous ventilation and heat dissipation operation, the temperature 3 in the fixed shell 11 gradually recovers, and the sliding plug 31 gradually moves in the reverse direction to reset.

[0030] If the temperature of the electromechanical equipment load increases and causes the sliding plug 31 to move and squeeze the pressure sensor 32, the pressure sensor 32 sends a signal to the control terminal. At this time, the control terminal appropriately increases the power of the electric fan 16 according to the temperature monitored by the temperature sensor 12, accelerates the gas flow, and thus enhances the cooling efficiency of the device on the electromechanical equipment, so that the electromechanical equipment is always at a suitable temperature, thereby extending the service life of the equipment.

[0031] After the temperature in the fixed shell 11 gradually decreases, the sliding plug 31 moves in the opposite direction to reset. At the same time, when the temperature sensor 12 detects that the temperature returns to the initial setting value, the control terminal adjusts the power of the electric fan 16 back to the initial value to reduce the overall energy consumption of the device.

[0032] Example 2: Based on Example 1, refer to Figure 3 , Figure 6 and Figure 7 As shown, it also includes: a truncated cone shell 4, which is fixedly connected to the air duct 15; a rotating frame 41, which is fixedly connected to the output shaft of the electric fan 16, and the filter screen on the air duct 15 and the truncated cone shell 4 are both in contact with the rotating frame 41; and a discharge shell 42, which is fixedly connected to the outer side of the truncated cone shell 4.

[0033] In the above scheme, the blades of the rotating frame 41 are inclined. When the electric fan 16 is working to guide the gas flow, the electric fan 16 drives the rotating frame 41 to rotate together. The rotation of the rotating frame 41 causes the gas to rotate in the truncated cone shell 4 before entering the air duct 15. The rotation of the gas and the rotation of the rotating frame 41 drives the impurities in the gas to gather near the inner wall of the truncated cone shell 4, reducing the dust impurities adhering to the filter screen of the air duct 15, keeping the gas flow rate in the air duct 15 constant, that is, keeping the heat dissipation effect stable. The impurities subsequently gathered on the inner wall of the truncated cone shell 4 are discharged through the discharge shell 42. The operator can selectively install this structure. When there is a lot of dust in the external environment (for example, in a flour mill), the dust in the gas can be pre-separated by installing this structure to ensure that the device can stably dissipate heat and cool the electromechanical equipment.

[0034] Example 3: Based on Example 2, refer to Figure 2 , Figure 6 and Figure 7 As shown, it also includes: a shell 5, which is fixed to the outer side of the protective box 1 through a bracket, an air guide pipe 15 is slidably connected to the fixed shell 13, and the truncated cone shell 4 is in contact with the shell 5; a limit rod 51, which is slidably set on the shell 5, and a tension spring is installed between the shell 5; a fixed block 52, which is fixed to the discharge shell 42, and the limit rod 51 is used to limit the movement of the fixed block 52; the fixed block 52 is provided with two inclined surfaces with different inclination angles, and the limit rod 51 is provided with a ball for reducing the friction between it and the fixed block 52.

[0035] In the above scheme, the upper surface of the fixed block 52 is divided into three sections, and the three sections are divided into two inclined surfaces and one horizontal surface. The inclination of the left inclined surface on the fixed block 52 is greater than the inclination of the right inclined surface, which is convenient for the operator to pull the cone shell 4, the discharge shell 42 and the fixed block 52 to move in the opposite direction and reset. The tension spring between the limit rod 51 and the shell 5 is always in a stretched state.

[0036] Reference Figure 3 and Figure 6 As shown, the air guide tube 2 15 is fixedly connected to the fixing frame 6, the air guide tube 1 14 is slidably connected to the fixing shell 2 13, the air guide tube 1 14 is fixedly connected to the fixing plate 61, the fixing plate 61 is provided with a guide groove, the fixing frame 6 slides in the guide groove of the fixing plate 61, and the air guide tube 2 15 is provided with an air guide hole 62, and the air guide hole 62 is used to change the flow path of the gas in the conduit 2.

[0037] In the above scheme, a one-way valve is installed in the duct 21, the sum of the "horizontal length" of the left inclined surface on the fixed block 52 and the "horizontal length" of the horizontal surface thereon is the same as the gap between the duct 2 and the air guide hole 62 (the horizontal length is the projection on the horizontal plane), the guide groove of the fixed plate 61 is divided into two sections, namely the horizontal groove and the inclined groove, the length of the horizontal groove on the fixed plate 61 is the same as the "horizontal length" of the left inclined surface on the fixed block 52, and the electric fan 16 is located on the left side of the air guide hole 62.

[0038] Specific working principle: when the device works in an environment with a lot of dust, as dust impurities adhere to the filter screen of the air duct 15 and the air duct 15 is gradually blocked, the adsorption force of the electric fan 16 on the air duct 15 gradually increases. When the adsorption force is greater than the limiting force of the limiting rod 51 on the fixed block 52, the fixed block 52 will squeeze the limiting rod 51 to move upward, and then the fixed block 52 drives the frustum shell 4, the discharge shell 42 and the air duct 15 to move to the left together.

[0039] When the limit rod 51 is located at the inclined surface on the right side of the fixed block 52, the limit rod 51 squeezes the right inclined surface of the fixed block 52 under the tension of the connected tension spring, so that the conical shell 4 and the air guide pipe 15 continue to move right, and the air guide pipe 15 drives the fixing frame 6 to move right to squeeze the inclined part of the guide groove on the fixing plate 61, so that the fixing plate 61 drives the air guide pipe 14 to move upward, and the air guide pipe 14 moves upward to release the connection with the fixed shell 11, and then the fixed shell 11 is connected with the interior of the protective box 1.

[0040] When the limit rod 51 moves to the tail end of the right inclined surface on the fixed block 52, the air duct 15 stops moving. At this time, the air duct 15 moves to connect the air guide hole 62 with the conduit 1 2. The subsequent operation of the electric fan 16 will allow the gas to re-enter the air duct 15 through the air duct 15, the fixed shell 13, the air duct 14, the protective box 1, the exhaust pipe 17, the conduit 1 2 and the air guide hole 62, so that the gas circulates internally, so that the device maintains a cooling effect for a period of time. The subsequent temperature change in the fixed shell 11 will repeat the above operation. After the electromechanical equipment is finished working, the operator closes the device, cleans the impurities on the air duct 15, and pulls the frustum shell 4 to move in the opposite direction to reset it.

[0041] Example 4: Based on Example 3, refer to Figure 2 , Figure 8 and Fig. 9 As shown, it also includes: a rotating plate 7, which has a plurality of them, and a side wall of the fixed shell 11 is provided with circumferentially distributed rectangular through holes, and the plurality of rotating plates 7 are respectively rotatably arranged in adjacent rectangular through holes on the fixed shell 11, and a spring is installed between the rotating plate 7 and the fixed shell 11; a sliding frame 71, which is slidably arranged on the outside of the fixed shell 11, and a tension spring is installed between the sliding frame 71 and the fixed shell 11, and the sliding frame 71 is used to limit all the rotating plates 7; a transmission member 72, which is installed on the fixed shell 11 On the outside, a wedge block 73 is slidably provided on the fixed shell 11, and the sliding frame 71 and the wedge block 73 are both connected to the transmission member 72. The transmission member 72 is used to control the moving direction of the sliding frame 71 to be the same as or opposite to the moving direction of the wedge block 73. The wedge block 73 is provided with an inclined surface, and the air guide tube 14 is used to squeeze the inclined surface of the wedge block 73; the multiple rotating plates 7 are divided into two groups, and the two groups of rotating plates 7 are cross-distributed. The rotating directions of the rotating plates 7 in the same group are the same, while the rotating directions of the rotating plates 7 in different groups are opposite.

[0042] In the above scheme, the spring connected to the sliding frame 71 is always in a compressed state, the fixed shell 11 has eight rectangular through holes equidistantly distributed in the circumferential direction, the edge of the rotating plate 7 is made of rubber, and the torsion spring between the rotating plate 7 and the fixed shell 11 is always in a torsion state, so that the rotating plate 7 always fits the sliding frame 71, the transmission member 72 is composed of a fixed frame, two racks and a gear, the sliding frame 71 is fixedly connected to the adjacent rack, the wedge block 73 is fixedly connected to another rack, and the inclined surface on the wedge block 73 is inclined downward from left to right (with the attached Figure 8 direction as an example), Attachment Fig. 9 It is a state diagram when the rotating plate 7 is working.

[0043] During the upward movement of the air duct 14, the air duct 14 will gradually release the restriction on the wedge block 73. At this time, under the elastic force of the spring connected to the sliding frame 71, the sliding frame 71 moves and gradually releases the restriction on the rotating plate 7. The rotating plate 7 gradually swings under the torsion of the torsion spring, and the rotating plate 7 releases the obstruction of the adjacent rectangular through hole on the fixed shell 11. The sliding frame 71 moves the wedge block 73 to the right through the transmission member 72. Then the gas ejected from the air duct 14 flows inside the protective box 1, and the flowing gas enters the fixed shell 11 through the rectangular through hole to dissipate heat and cool down the electromechanical equipment. The gas after subsequent heat absorption enters the exhaust pipe 17, and the above gas cycle is repeated.

[0044] During the internal circulation of gas, if the temperature in the fixed shell 11 rises, the above-mentioned operation of controlling the rotation of the electric parts in the air guide pipe 14 will be repeated to make the gas rotate in the protective box 1. The rotating gas passes through eight rotating plates 7 with staggered tilt angles, so that the rotating gas blows back and forth on the electromechanical equipment. At the same time, under the principle of "thermal centrifugal effect", the gas rotation causes the temperature of the gas in the box 1 to be stratified, and the low-temperature gas is gathered near the electromechanical equipment to avoid the electromechanical equipment from working at high temperatures, thereby extending the service life of the electromechanical equipment.

[0045] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope provided by the present invention, which should be covered within the protection scope of the present invention.
