Description

Technical Field

[0001] The utility model relates to the technical field of secondary water supply, in particular to a flood prevention system for an outdoor pumping station. Background Technique

[0002] As an infrastructure supporting social and economic development, the urban water supply system is becoming increasingly important. Especially in modern agricultural irrigation, the expansion of urban water supply networks, and the construction of emergency drainage systems, the demand for efficient, energy-saving, and intelligent micro pumping stations has increased sharply. However, due to inherent defects such as large floor area, high energy consumption, complex maintenance, and high cost, traditional pumping stations have been difficult to meet the current and future social needs for intelligent and refined water resource management.

[0003] Especially in rural areas, communication base stations, and outdoor environments with harsh conditions where it is difficult to build fixed pump houses, the application of micro pumping stations is particularly important. However, these areas often face challenges such as complex and changeable natural conditions and frequent extreme weather (such as severe waterlogging caused by heavy rainstorms), which pose extremely high requirements for the flood prevention ability and stable operation of micro pumping stations.

[0004] Most micro pumping stations on the market today, although striving to be compact and efficient, generally lack an effective flood prevention system. Once affected by floods or heavy rains, it is extremely easy to have problems such as water ingress into the pump motor, and the pump group base and inlet pipe fittings being soaked by water, which not only seriously affects the normal operation of the pumping station, but also causes waste of water resources and damage to equipment.

[0005] In addition, in the high-temperature environment in summer, due to the compact structure and limited internal space of micro pumping stations, the heat dissipation problem is particularly prominent. The heat dissipation systems of some micro pumping stations on the market are not yet mature, and it is difficult to effectively cope with the challenges brought by high-temperature environments, resulting in accelerated aging of electrical circuits, too high temperatures inside the motor and control cabinet, and further triggering safety hazards such as overheat protection activation, motor damage, and even short circuits in the control cabinet lines, seriously affecting the service life and operation stability of the pumping station.

[0006] In order to solve at least one of the above technical problems, the utility model proposes a flood prevention system for an outdoor pumping station. Content of the Utility Model

Specific embodiments

[0047] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present utility model will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repeated description will be omitted.

[0048] The words expressing positions and directions described in the present utility model are all illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all the changes made are included in the protection scope of the present utility model.

[0049] Aiming at the two key problems of insufficient flood prevention ability and poor performance of the heat dissipation system existing in the current outdoor micro-pumping station, the present utility model introduces a flood prevention system for an outdoor pumping station. In order to improve the waterproof performance of the outdoor pumping station, the flood prevention system of the present utility model includes: a machine shell 1, a drainage assembly, and a liquid level detection assembly. Further, in order to improve the heat dissipation performance of the outdoor pumping station, the flood prevention system of the present utility model may further include: a heat dissipation assembly. Furthermore, in order to improve the stability and drainage effect of the outdoor pumping station, the flood prevention system of the present utility model may further include: a bracket 6.

[0050] Refer to Figure 1, the housing 1 of the present utility model includes a shell and a partitioned wire outlet plate 13. The partitioned wire outlet plate 13 divides the shell into an independent first shell 121 and a second shell 122. The first shell 121 is located above the second shell 122. The first shell 121 houses the electrical part, and the second shell 122 houses the unit part. The water inlet 202 and the water outlet 201 of the unit part are both installed on the second shell 122. By separately arranging the electrical part and the unit part of the outdoor pump station in the independent and position-separated first shell 121 and second shell 122, the potential electrical and water immersion risks are effectively isolated.

[0051] In some preferred embodiments, the second shell 122 includes a top plate 1221, a bottom plate 1222, and side plates 1223. The top plate 1221 is connected to the first end of the side plates 1223 and is connected to the first shell 121. The bottom plate 1222 is connected to the second end of the side plates 1223 opposite to the first end.

[0052] The drainage assembly of the present utility model is arranged on the second shell 122 and below the unit part to prevent water accumulation from damaging the unit part.

[0053] In some preferred embodiments, referring to Figure 2 , the drainage assembly includes: a lower drainage hole 41 and a side drainage hole 42. The side drainage hole 42 is arranged on the side plate 1223 and below the motor 200, which can effectively drain the accumulated water around the motor 200, prevent the motor 200 from being damaged by moisture and short-circuit, and improve the overall waterproof performance of the system and the safety of the operation of the motor 200. Further, the distance between the side drainage hole 42 and the motor 200 is greater than or equal to a fifth preset threshold, where the fifth preset threshold is greater than 0. Those skilled in the art can set the minimum distance between the side drainage hole 42 and the motor 200 according to the actual situation, that is, the size of the fifth preset threshold, so as to ensure the drainage effect while avoiding adverse effects on the motor 200 when the drainage hole drains water, further improving the safety and reliability of the system. In addition, the lower drainage hole 41 is arranged on the bottom plate 1222, so that the accumulated water can be quickly discharged from the bottom, avoiding the immersion of the unit part by the accumulated water. In actual application, multiple lower drainage holes 41 and side drainage holes 42 can be arranged.

[0054] The bracket 6 of the present utility model is arranged below the bottom plate 1222, which can not only improve the support performance of the system, but also make the distance between the bottom plate 1222 and the ground greater than or equal to a fourth preset threshold, where the fourth preset threshold is greater than 0. Those skilled in the art can flexibly adjust the size of the fourth preset threshold according to the actual site conditions to adapt to different drainage requirements and waterproof standards, improve the adaptability and flexibility of the system, and further enhance the drainage effect and waterproof ability.

[0055] In some preferred embodiments, a crossbeam is provided on the bracket 6, and a plurality of water pipes adapted to the lower drain holes 41 are arranged on the crossbeam, so as to introduce the accumulated water in the second housing 122 into an external water storage unit, which can not only prevent the discharged water from entering the second housing 122 again, but also recycle the accumulated water for secondary use, thus saving water resources.

[0056] The liquid level detection component of the present utility model is arranged below the unit part. The liquid level detection component is connected to an external protection circuit, which can monitor the water level situation below the unit part in real time. Once the water level exceeds the safety threshold, an alarm will be triggered or the external power supply F0-1 will be cut off through the connected external protection circuit, thereby preventing the equipment from continuing to operate at a dangerous water level and reducing equipment damage and potential safety accidents caused by waterlogging.

[0057] In some preferred embodiments, referring to Figure 4 , the protection circuit includes an alarm LB and a contactor KM connected in parallel, and the alarm LB is connected in series with the first relay switch KA33, and the contactor KM is connected in series with the second relay switch KA34. Among them, the first relay switch KA33 is in a normally open state, and the second relay switch KA34 is in a normally closed state. Referring to Figure 5 , one end of the contactor KM is connected to the motor 200, and the other end of the contactor KM is connected to the incoming line terminal block TX1 connected to the external power supply F0-1. It can be seen that the contactor directly controls the external power supply F0-1 of the motor 200. When a dangerous water level is detected, the external power supply F0-1 can be quickly cut off to prevent the motor 200 from continuing to operate in a dangerous environment, thereby protecting the motor 200 from waterlogging damage and extending the service life of the equipment.

[0058] In some preferred embodiments, the liquid level detection assembly includes: a first liquid level sensor 31 and a second liquid level sensor 32. The second liquid level sensor 32 is disposed above the first liquid level sensor 31 and below the motor 200. By providing the first liquid level sensor 31 and the second liquid level sensor 32 at two different heights and combining the parallel-connected alarm LB and contactor KM, a hierarchical response mechanism can be achieved. When the water level reaches a lower threshold, an alarm is triggered to remind maintenance; when the water level continues to rise to a higher threshold, the external power supply F0-1 of the motor 200 is automatically cut off to prevent damage to the motor 200, further improving the safety and intelligence level of the flood prevention system. Further, the distance between the first liquid level sensor 31 and the ground is greater than or equal to a first preset threshold; the distance between the first liquid level sensor 31 and the second liquid level sensor 32 is greater than or equal to a second preset threshold; the distance between the second liquid level sensor 32 and the motor 200 is greater than or equal to a third preset threshold; wherein, the first preset threshold, the second preset threshold, and the third preset threshold are all greater than 0. Those skilled in the art can, by setting the preset thresholds between each sensor and the motor 200, not only avoid false alarms but also ensure that the system can take appropriate protection measures under different water level conditions, ensuring the accuracy and timeliness of the system response, and further improving the reliability and stability of the system.

[0059] In actual application, both the first liquid level sensor 31 and the second liquid level sensor 32 are float reactors. The first liquid level sensor 31 is placed at the height of the water inlet 202 of the water pump, and the second liquid level sensor 32 is disposed at a position 30-50 mm below the motor.

[0060] In some preferred embodiments, the first liquid level sensor 31 is connected to the alarm. Specifically, referring to Figure 3 , the first liquid level sensor 31 is connected to a first relay switch KA33 connected in series with the alarm. When the first liquid level sensor 31 does not detect the water level, the common terminal and the control terminal of the first liquid level sensor 31 are open, and the first relay switch KA33 is in the normally open state; when the first liquid level sensor 31 detects the water level, the common terminal and the control terminal of the first liquid level sensor 31 are short-circuited, and the first relay switch KA33 closes. At this time, the alarm emits an alarm signal. In actual application, the alarm signal will be transmitted to the control cabinet and then to the manufacturer's total monitoring network.

[0061] In some preferred embodiments, the second liquid level sensor 32 is connected to the contactor. Specifically, referring to Figure 3, the second liquid level sensor 32 is connected to a second relay switch KA34 in series with the contactor. When the second liquid level sensor 32 does not detect the water level, the common terminal and the control terminal of the second liquid level sensor 32 are open, and the second relay switch KA34 is in the normally closed state. At this time, the unit can operate normally; when the second liquid level sensor 32 detects the water level, the common terminal and the control terminal of the second liquid level sensor 32 are short-circuited, and the second relay switch KA34 is opened. At this time, the contactor directly cuts off the external power supply F0-1 of the control motor 200 to prevent the motor 200 from continuing to operate in a dangerous environment.

[0062] The heat dissipation component of the present utility model includes: a first heat dissipation fan 51 and a second heat dissipation fan. Further, the heat dissipation component may further include: a first exhaust grille 53 and a second exhaust grille 54. By providing the heat dissipation component, the ventilation conditions inside the device can be effectively improved, the heat accumulation generated during the operation of the device can be reduced, the heat dissipation efficiency and operation stability of the device can be improved, and the service life of the device can be extended.

[0063] In some preferred embodiments, the first heat dissipation fan 51 and the first exhaust grille 53 are both provided on the first housing 121; the second heat dissipation fan and the second exhaust grille 54 are provided on the second housing 122. By providing exhaust grilles on the first housing 121 and the second housing 122 respectively, independent heat dissipation channels are formed to dissipate heat for the electrical part and the unit part respectively, improving the heat dissipation efficiency, reducing the cross-influence of heat, and further ensuring the normal operation and stability of the device.

[0064] In summary, the present utility model separately arranges the electrical part and the unit part in the mutually independent and spatially separated first housing 121 and second housing 122, effectively isolating the electrical components and the unit components, reducing the risk of electrical short circuits and mechanical failures caused by waterlogging. Even if the external environment is flooded, it can protect the internal equipment from damage to a certain extent. In addition, the drainage component of the present utility model can quickly drain the accumulated water in the second housing 122, and the detection component can monitor the water level situation below the unit part in real time. Once the water level exceeds the safety threshold, an alarm will be triggered or the external power supply F0-1 will be cut off through the connected external protection circuit, thereby preventing the device from continuing to operate at a dangerous water level and reducing equipment damage and potential safety accidents caused by waterlogging.

[0065] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Without departing from the principle and purpose of the present utility model, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model, and all these changes should fall within the protection scope of the claims of the present utility model.
