Description

TECHNICAL FIELD

[0001] The present application relates to the field of electrical control boxes, in particular to a low-temperature water pump control box. BACKGROUND

[0002] The low-temperature water pump control box on the ship is a crucial device in the ship pipeline system, mainly used for automatic control and monitoring of the running state of the low-temperature water pump, to ensure the stable operation of the ship low-temperature system (such as cooling system, air conditioning system, etc.). The box body of the low-temperature water pump control box is usually made of waterproof, dustproof and corrosion-resistant materials to meet the environmental requirements of ship cabin humidity and vibration, and the protection level can reach IP54 and above. When the low-temperature water pump control box is running, the frequency converter, relay, contactor and other electrical components inside the box body will generate heat, which may cause overheating and failure of the components if the heat dissipation is poor, affecting the reliability of the control box. Therefore, the low-temperature water pump control box for ships needs to provide good heat dissipation conditions while ensuring protection effect.

[0003] The existing low-temperature water pump control box for ships is equipped with a corresponding heat dissipation system, the core of which is to avoid heat accumulation inside the box body through the exchange of internal and external air flow. However, the air condition on the ship is humid, and the heat dissipation system on the low-temperature water pump control box for ships needs to have a moisture-proof function while achieving ventilation and heat dissipation. Therefore, the ventilation holes opened on the existing low-temperature water pump control box for ships also need to meet the protection level of IP54 and above, which is achieved by setting a labyrinth-like channel to block dust and water flow. However, this moisture-proof method still cannot prevent humid air from entering the control box, which increases the risk of damage to electrical components.

[0004] In view of the problem that humid air increases the probability of damage to the control box, a moisture-proof electrical component control box is disclosed in Chinese Patent No. CN118336549A, which uses a technical solution of setting a fiber moisture-absorbing bag on the ventilation path to achieve the effect of drying the air flow entering the electrical component control box to prevent the electrical components from being damp. However, in actual use conditions, on the one hand, when the heat in the control box accumulates quickly, in order to diffuse the heat dissipation air flow to the entire space inside the control box, thereby fully and quickly dissipating the high-temperature gas inside the control box, the air flow rate and flow rate of the heat dissipation air flow entering the control box need to be high, on the other hand, the drying of high-humidity air by the moisture-absorbing material needs time, which results in limited drying effect when the air flow quickly passes through the moisture-absorbing material. Therefore, only setting a moisture-absorbing piece on the ventilation path cannot balance the moisture-proof effect and heat dissipation effect, and the present application proposes a low-temperature water pump control box. SUMMARY

[0005] The purpose of the present application is to provide a low-temperature water pump control box to solve the above problems.

[0006] The application achieves the above-mentioned purpose through the following technical solutions. The application provides a low-temperature water pump control box, which comprises a box body of the control box, an in-box environment monitor, a ventilation and heat dissipation mechanism and a controller. The moisture-proof assembly comprises a wind guide disc, a side cover, a ventilation cover rotatably installed in the wind guide disc, an elastic body arranged on the inner side of the ventilation cover, a ventilation control piece for controlling the opening and closing of the air port of the elastic body, and a barrier net arranged on the outer side of the ventilation cover. The elastic body is used for deflating to open the ventilation cover when the rapid moisture-proof heat dissipation treatment is performed, so that the airflow rapidly passes through the honeycomb zeolite molecular sieve from inside to outside, and the elastic body is inflated to block the ventilation cover when the regular moisture-proof heat dissipation treatment is performed, so that the airflow passes through the entire honeycomb zeolite molecular sieve along the distribution arc line of the honeycomb zeolite molecular sieve.

[0007] As a further optimization scheme of the application, the ventilation cover comprises a support rotatably connected with the wind guide disc and in the shape of a ring, and two net covers arranged in a double-layered manner on one side of the support. The elastic body comprises a capsule in the shape of a ring and a plurality of flexible connecting pieces arranged in a ring array in the capsule.

[0008] As a further optimization scheme of the application, the ventilation control piece comprises a wind guide pipe and a blocking block arranged on the inner side of the wind guide pipe.

[0009] As a further optimization scheme of the application, the wind guide disc is embedded with an electromagnetic block matched with the ventilation control piece.

[0010] As a further optimization scheme of the application, the inner side of the ventilation cover is provided with a gear ring, and the wind guide disc is provided with a driving gear engaged with the gear ring and a driving piece.

[0011] As a further optimization scheme of the application, the air inlet assembly comprises an air inlet pipe communicated with the wind guide disc, an air inlet disc arranged below the box body and communicated with the box body, and an air inlet air pump communicated with the air inlet pipe and the air inlet disc.

[0012] As a further optimization of the present invention, the exhaust assembly includes an exhaust fan, an exhaust air pump, a pipeline environment monitor, a three-way valve, and a return pipe connected in sequence. The return pipe is connected to the air guide fan, the exhaust fan is located above the housing and is connected to the housing, and the three-way valve is also connected to the exhaust pipe.

[0013] As a further optimization of the present invention, the honeycomb zeolite molecular sieve is embedded with a number of uniformly distributed heating columns, and the side cover is provided with a power supply component and a conductive sheet corresponding to each heating column.

[0014] As a further optimization of the present invention, the air guide plate is provided with several mounting sleeves, and the side cover and the air guide plate are detachably connected by bolts and mounting sleeves.

[0015] The beneficial effects of this invention are as follows: 1. By combining the air guide plate, ventilation hood, and elastomer, the ventilation path of the air guide plate is altered through the deflation and inflation of the elastomer, thereby changing the path of the gas through the honeycomb zeolite molecular sieve. This provides two modes of airflow protection for the control box: conventional moisture-proof and heat dissipation treatment and rapid moisture-proof and heat dissipation treatment. In the conventional moisture-proof and heat dissipation treatment mode, the airflow must pass through the entire honeycomb zeolite molecular sieve along the arc path distributed by the honeycomb zeolite molecular sieve. The gas can fully contact the honeycomb zeolite molecular sieve, resulting in a comprehensive and significant cooling and dehumidification effect. This is suitable for control boxes that are frequently exposed to moisture during operation due to the movement of internal components. In the case of a temperature rise, under the rapid moisture-proof and heat dissipation mode, the gas passes directly through the honeycomb zeolite molecular sieve from the inside to the outside. The path is short, which can achieve a large flow rate and high speed ventilation effect. It is suitable for emergency situations where the temperature inside the control box is too high. After emergency heat dissipation, the moisture-proof component can quickly switch to the normal moisture-proof and heat dissipation mode. Thus, the gas that was not completely dried due to the rapid passage through the honeycomb zeolite molecular sieve during the rapid moisture-proof and heat dissipation stage is circulated in and out. During the gas circulation process, it is repeatedly absorbed and dried. This is a complete heat dissipation and moisture-proof treatment process, which has the advantages of being timely, efficient and comprehensive.

[0016] 2. During the conventional moisture-proof and heat dissipation process, the honeycomb zeolite molecular sieve only needs to cool and dehumidify the gas circulating in and out of the control box. There is no need to introduce air from the outside. Compared with the method of continuously using external airflow for ventilation and heat dissipation, the cooling and dehumidification burden of the honeycomb zeolite molecular sieve is greatly reduced, the service life of the honeycomb zeolite molecular sieve is extended, and the efficiency of temperature and humidity control of the gas inside the box can be improved.

[0017] 3. By combining the heating column and the honeycomb zeolite molecular sieve, the honeycomb zeolite molecular sieve can be revitalized by high-temperature heating after the moisture-proof and heat-dissipating treatment is completed, which helps to further improve durability and reduce usage costs.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1 like Figures 1-8 As shown, the cryogenic water pump control box of this embodiment includes a control box body, an internal environment monitor 1, a ventilation and heat dissipation mechanism, and a controller. The selection standard of the body is the same as that of the existing cryogenic water pump control box, and the protection level is IP54 or above. The ventilation and heat dissipation mechanism includes an air inlet component, an air outlet component, and a moisture-proof component. The moisture-proof component is used to dissipate heat and prevent moisture from the gas entering and leaving the body. The moisture-proof component includes an air guide plate 4, a side cover 19, a ventilation hood 7 rotatably installed in the air guide plate 4, an elastic body 8 (inflatable rubber ring, inflatable air bag, etc.) located inside the ventilation hood 7, a ventilation control component 10 for controlling the opening and closing of the air vents of the elastic body 8, and a baffle net 9 located outside the ventilation hood 7. The side cover 19 has a mesh structure in the center. The baffle net 9, together with the ventilation control component 10, divides the annular space outside the ventilation hood 7 into a dehumidification groove 12 and a ventilation groove 13. The dehumidification groove 12 is filled with a honeycomb zeolite molecular sieve 14. The elastomer 8 is used to release air during rapid moisture-proof and heat-dissipating treatment to open the ventilation hood 7, allowing airflow to pass quickly from the inside to the outside through the honeycomb zeolite molecular sieve 14, and to inflate air during conventional moisture-proof and heat-dissipating treatment to seal the ventilation hood 7, allowing airflow to pass through the entire honeycomb zeolite molecular sieve 14 along the distribution arc of the honeycomb zeolite molecular sieve 14.

[0022] The air intake assembly includes an air intake pipe 5 connected to the air guide plate 4, an air intake plate 2 located below the box and connected to the box, and an air intake pump 21 connecting the air intake pipe 5 and the air intake plate 2. The exhaust assembly includes an exhaust fan plate 3, an exhaust air pump 22, a pipeline environment monitor 23, a three-way valve 24 and a return pipe 6 connected in sequence. The return pipe 6 is connected to the air guide plate 4. The exhaust fan plate 3 is located above the box and is connected to the box. The three-way valve 24 is also connected to an exhaust pipe 25. The in-box environment monitor 1 and the pipeline environment monitor 23 are used to monitor the gas temperature, heating rate and humidity in the in-box and exhaust duct respectively; The internal environment monitor 1, pipeline environment monitor 23, air intake pump 21, air exhaust pump 22, three-way valve 24, and electromagnetic block 11 are all electrically connected to the controller, and the controller is connected to the control system of the water pump control box.

[0023] When the water pump control box is not running, both the air intake component and the air exhaust component are in the closed state, that is, the air intake pump 21 and the air exhaust pump 22 are both closed, the box is in a sealed state, the elastomer 8 is in an inflated state, and the outside air cannot come into contact with the honeycomb zeolite molecular sieve 14. When the water pump control box starts running, it is in normal moisture-proof and heat-dissipating mode, that is, the passage between the air intake pump 21 and the exhaust pump 22 to the return pipe 6 is opened. At this time, the gas in the box will pass through the air guide plate 4 and circulate under the action of the air intake pump 21 and the exhaust pump 22. When the gas passes through the air guide plate 4, since the elastic body 8 is in an inflated state, the air guide plate 4 is not connected to the outside. Therefore, the airflow can only enter from the return pipe 6 and pass through the honeycomb zeolite molecular sieve 14 in the ventilation slot 13 and the dehumidification slot 12 in sequence. The honeycomb zeolite molecular sieve 14 can cool the airflow. The cooled airflow is then transported back into the box under the action of the air intake pump 21. In this way, the gas in the box can be continuously cooled, avoiding the problem of heat accumulation in the box. When the temperature inside the water pump control box rises rapidly and reaches the preset alarm value for the temperature rise rate of the internal environment monitor 1, the system switches from normal moisture-proof and heat dissipation mode to rapid moisture-proof and heat dissipation mode. The specific process includes the following stages: (1) Keep the air intake pump 21 on, close the passage between the exhaust air pump 22 and the exhaust fan 3 to the return pipe 6, and open the ventilation control component 10 to connect the elastomer 8 with the ventilation slot 13. During this stage, the air intake pump 21 will draw gas from the dehumidification slot 12, the ventilation slot 13 and the elastomer 8, and the elastomer 8 will gradually degas until it is dry and flat, thereby opening the ventilation cover 7. During this process, the gas drawn out will enter the box through the air intake path, causing the air pressure inside the box to rise slightly, but it will not affect the operation of the water pump control box. (2) Restart the exhaust air pump 22 and open the passage between the three-way valve 24 and the exhaust pipe 25, as well as the drive assembly of the ventilation hood 7, so that the ventilation hood 7, the honeycomb zeolite molecular sieve 14, the baffle net 9 and the ventilation control component 10 are connected to rotate as a whole. At this time, the outside air can pass through the side cover 19 and the ventilation hood 7 and enter the air guide plate 4. It passes through the local honeycomb zeolite molecular sieve 14 facing the air inlet pipe 5 from the inside to the outside and enters the air inlet pipe 5. Finally, it is transported to the box. The high temperature gas in the box will be squeezed upward and discharged through the exhaust plate 3, the exhaust air pump 22, the pipeline environment monitor 23, the three-way valve 24 and the exhaust pipe 25. This can achieve the effect of rapid heat dissipation. The uprights entering the box can also be preliminarily dehumidified and dried. Since the honeycomb zeolite molecular sieve 14 rotates continuously, the dehumidification effect of each part of the honeycomb zeolite molecular sieve 14 can be kept uniform. (3) When the environment monitor 1 detects that the temperature inside the box drops below the alarm value, after the honeycomb zeolite molecular sieve 14, the baffle net 9 and the ventilation control component 10 are connected and rotated back to the initial position, the drive component of the ventilation cover 7 is closed, the passage to the exhaust pipe 25 is closed and the passage between the exhaust plate 3 and the return pipe 6 is opened. At the same time, the ventilation control component 10 is opened. In this state, the airflow entering the ventilation slot 13 will partially enter the elastomer 8. After the elastomer 8 is fully expanded, the ventilation control component 10 is closed, so that the exhaust plate 3 can be restored to the normal moisture-proof and heat dissipation state.

[0024] As can be seen from the above usage process, the water pump control box can provide two ventilation and heat dissipation methods according to the temperature conditions inside the box: rapid heat dissipation and conventional heat dissipation. During the ventilation and heat dissipation process, the airflow can also be dehumidified, so that the water pump control box can have both heat dissipation and moisture-proof effects.

[0025] Preferably, the ventilation hood 7 includes a bracket 701 that is rotatably connected to the air guide plate 4 and is in the shape of an annular structure, two mesh covers 702 that are distributed in a double layer on one side of the bracket 701, and an elastic body 8 that is in the shape of an annular structure and is disposed between the two mesh covers 702. The elastomer 8 includes a ring-shaped capsule 801 and a plurality of flexible connectors 802 (elastic ropes) arranged in a ring array inside the capsule 801. One side of the capsule 801 is attached and fixed to the support 701, and the flexible connectors 802 are arranged parallel to the central axis of the ventilation hood 7. When no gas is injected into the elastomer 8, the elastomer 8 is in a flattened state under the pull of the flexible connector 802, located deep within the ventilation hood 7. At this time, the mesh cover 702 is not blocked (e.g., Figure 8 As shown on the left), ventilation is possible; when the elastomer 8 gradually deflates from its inflated state, the rebound of the flexible connector 802 further accelerates the deflation process, causing the elastomer 8 to quickly return to its flattened state; after the elastomer 8 inflates and expands, it gradually fills the space between the two mesh covers 702, ultimately achieving the effect of closing the ventilation cover 7 (as shown on the left). Figure 8 (As shown on the right) It should be emphasized that during the above stage (3), when the elastomer 8 gradually expands, the ventilation hood 7 is still in the open state. Therefore, the gas entering the ventilation slot 13 will partially enter the elastomer 8, partially enter the honeycomb zeolite molecular sieve 14, and partially overflow through the ventilation hood 7. However, the overall size of the elastomer 8 is small, and the amount of gas and the gas pressure required for expansion are both small. Therefore, it can gradually expand even when only a portion of the airflow enters, so that the ventilable area of ​​the ventilation hood 7 gradually decreases until it is completely closed. Furthermore, the area on the mesh cover 702 aligned with the ventilation slot 13 can be set as a non-mesh structure so that the airflow can rush into the elastomer 8 more quickly.

[0026] Preferably, the ventilation control component 10 includes an air guide duct 101 and a blocking block 102 disposed inside the air guide duct 101. The blocking block 102 is elastically slidably connected to the air guide duct 101 by a spring. One end of the air guide duct 101 is attached to the inner wall of the air guide plate 4, and the other end passes through the side wall of the outer mesh cover 702 and the bag body 801 and is fixed on the bag body 801. The side of the air guide duct 101 facing the ventilation slot 13 has an open structure. The air guide plate 4 is embedded with an electromagnetic block 11 that cooperates with the ventilation control component 10. Both the air intake component and the air exhaust component are connected to the air guide plate 4, and the electromagnetic block 11 is located between the two ventilation openings.

[0027] Under normal conditions, under the action of the spring, one end of the sealing block 102 extends into the elastomer 8 to seal it. After the ventilation control component 10 is aligned with the electromagnetic block 11, the electromagnetic block 11 is activated. Under the attraction of the electromagnetic block 11, the sealing block 102 slides sideways, and the inlet of the elastomer 8 opens (e.g., Figure 7 As shown), gas can enter the elastomer 8 to achieve inflation and deflation. When the electromagnetic block 11 is closed, the elastomer 8 can be restored to a sealed state.

[0028] Preferably, the ventilation hood 7 has a toothed ring 16 on its inner side, and the air guide plate 4 has a drive gear 17 that meshes with the toothed ring 16 and a drive component. The drive component is a motor with an integrated angle sensor.

[0029] Preferably, the honeycomb zeolite molecular sieve 14 is embedded with a plurality of uniformly distributed heating columns 15, and the side cover 19 is provided with a power supply component and a conductive sheet 20 corresponding to each heating column 15. After the water pump control box returns from the running state to the non-running state, the conductive sheet 20 is in contact with the heating column 15. At this time, the ventilation control component 10 can be turned on to release the air from the elastomer 8. The ventilation hood 7 is opened, and then the power supply is turned on. The heating column 15 gradually heats up and heats the honeycomb zeolite molecular sieve 14 to restore its cooling and moisture absorption effect. The hot air from the heated rope is discharged through the ventilation hood 7. After completion, the corresponding operations in the above process are repeated to restore the elastomer 8 to its expanded state.

[0030] Preferably, the air guide plate 4 is provided with several mounting sleeves 18, and the side cover 19 is detachably connected to the air guide plate 4 by bolts and mounting sleeves 18. This facilitates the maintenance of the moisture-proof components and the replacement of the honeycomb zeolite molecular sieve 14 after long-term use. The air guide plate 4 can be removed and the honeycomb zeolite molecular sieve 14 and the heating column 15 can be directly extracted as a whole. The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
