Description

Technical Field

[0001] This utility model belongs to the field of equipment protection technology, specifically relating to a centrifugal pump protection device. Background Technology

[0002] Centrifugal pumps are widely used in industries such as chemical, metallurgical, and water treatment to transport various corrosive media and suspensions containing solid particles. In actual installation, the location and environment of centrifugal pumps vary. They may be installed indoors or outdoors. When installed outdoors, centrifugal pumps are unprotected and will be damaged more quickly under long-term exposure to wind and sun.

[0003] For example, Chinese Patent Publication No. CN 212202585 U discloses a vertical centrifugal pump protective device, which includes a drive motor. A dustproof cover adapted to the drive motor is welded to the top of the drive motor via a bracket. A connecting plate is horizontally welded to the outer wall of the bottom of the drive motor. Vertically downward fixing bolts are welded to the four corners of the bottom of the connecting plate, and these bolts are inserted into a first fixing plate with holes at the four corners. The centrifugal pump's interface is fitted with a rubber sleeve before installation to prevent dust from falling into the centrifugal pump.

[0004] As described in the aforementioned patent, when protecting a centrifugal pump, although setting a dust cover only on the top can achieve the effect of dust prevention, the lack of protective components around the pump body results in the dust prevention effect not achieving the expected effect and the protection effect being poor. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal pump protection device that can provide comprehensive protection for centrifugal pumps, effectively preventing dust and rain, reducing corrosion caused by long-term exposure to wind and sun when centrifugal pumps are working outdoors, and extending their service life.

[0006] The specific technical solution adopted in this utility model is as follows: A centrifugal pump protection device includes a base on which a centrifugal pump body and an outer cover are mounted. The outer cover is located outside the centrifugal pump body, and a protective cover is installed on the top of the outer cover. A water level sensor and a temperature sensor are installed on the side of the outer cover. An air inlet and an air outlet are respectively opened on the side of the outer cover. An air intake mechanism is installed outside the air inlet, and a first filter mechanism is installed outside the air intake mechanism. A second filter mechanism is installed on the outer side of the air outlet. A control mechanism for equipment control is provided on the outer side of the outer cover.

[0007] In a preferred embodiment, the outer cover is further provided with an installation port 1 for installing connecting pipe 1 and an installation port 2 for installing connecting pipe 2.

[0008] In a preferred embodiment, the air intake mechanism includes a housing connected to the air intake, a drive mechanism is installed inside the housing, and fan blades are mounted on the output shaft of the drive mechanism.

[0009] In a preferred embodiment, the first filtration mechanism includes a filter housing connected to the outer shell, a filter cotton is disposed inside the filter housing, and a cover is installed on the outer end of the filter housing. The second filtration mechanism includes a filter housing connected to the outer end of the exhaust port, a filter cotton is disposed inside the filter housing, and a cover is installed on the outer end of the filter housing.

[0010] In a preferred embodiment, an alarm mechanism is installed on the outer side of the outer cover, the alarm mechanism including an audible alarm unit and a visual alarm unit.

[0011] In a preferred embodiment, the control mechanism includes a signal analysis unit and a signal transmission unit, the signal transmission unit including a wired transmission module and a G transmission module.

[0012] The technical effects achieved by this utility model are as follows: This utility model provides all-around protection for the centrifugal pump body by installing an outer cover and protective cover on the outside of the pump body and mounting them on a base. The outer cover has an air inlet and an air outlet, allowing outside air to flow through it and dissipating heat. The installation of a filter mechanism one at the air inlet and a filter mechanism two at the air outlet helps prevent dust and reduces the risk of reduced lifespan of the centrifugal pump body installed outdoors due to wind and sun exposure.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0019] Please see the appendix Figures 1 to 3 As shown, this utility model provides a centrifugal pump protection device, including a base 1, on which a centrifugal pump body 4 and an outer cover 2 are mounted. The outer cover 2 is located outside the centrifugal pump body 4, and a protective cover 3 is mounted on the top of the outer cover 2. A water level sensor 8 and a temperature sensor 9 are mounted on the side of the outer cover 2. An air inlet 23 and an air outlet 24 are also provided on the side of the outer cover 2. An air inlet mechanism 5 is mounted on the outside of the air inlet 23, and a filter mechanism 6 is mounted on the outside of the air inlet mechanism 5. A filter mechanism 7 is also mounted on the outer side of the air outlet 24. A control mechanism 10 for equipment control is provided on the outer side of the outer cover 2. In this embodiment, when installing the centrifugal pump body 4, the centrifugal pump body 4 is first fixedly installed on the base 1, and then the outer cover 2 is covered on the outside of the centrifugal pump body 4. When in use, the air intake mechanism 5 draws outside air into the outer cover 2 through the air inlet 23 and exhausts it from the exhaust port 24. The internal and external air flow carries away the heat generated by the centrifugal pump body 4 during operation, thereby achieving the purpose of heat dissipation for the centrifugal pump body 4. When outside air enters from the air inlet 23, it is first filtered by the filter mechanism 6 to prevent dust from entering the outer cover 2 and contaminating the centrifugal pump body 4, thus playing a protective role. In this application, the base 1 can be precast concrete or a suitable mounting platform. The centrifugal pump body 4 and the outer cover 2 are installed on the base 1 by bolts. The protective cover 3 is installed on the top of the outer cover 2 by bolts. Its structure is conical, which can serve as a rain shield and facilitates rainwater to flow down quickly along the conical structure. It is worth noting that a water level sensor 8 and a temperature sensor 9 are installed on the side of the outer casing 2. The temperature sensor 9 can monitor the temperature inside the outer casing 2 in real time and transmit the signal to the control mechanism 10. The control mechanism 10 adjusts the output power of the air intake mechanism 5 to regulate the air intake volume, which facilitates energy-saving operation of the equipment. The water level sensor 8 can detect whether there is water accumulation inside the outer casing 2 and transmit the detection signal to the control mechanism 10 for signal analysis and identification.

[0020] Please refer to Figure 1 and Figure 4 As shown, the outer cover 2 is also provided with a mounting port 21 for mounting the connecting pipe 41 and a mounting port 22 for mounting the connecting pipe 42. In this application, the outer cover 2 is provided with mounting ports 21 and 22 that match the connecting pipe 41 and the connecting pipe 42, respectively. The connecting pipe 41 and the connecting pipe 42 have similar structures. The connecting pipe 41 is inserted into the outer cover 2 through the mounting port 21 and is fixedly connected to the centrifugal pump body 4. The outer cover 2 is then fixed in place. This prevents large gaps in the outer cover 2 due to the insertion of the connecting pipe, thereby improving the sealing performance of the outer cover 2. The connecting pipe 41 and the connecting pipe 42 are respectively connected to the inlet and outlet of the centrifugal pump body 4.

[0021] The air intake mechanism 5 includes an outer shell 51 connected to the air inlet 23. A drive mechanism 53 is installed inside the outer shell 51, and a fan blade 52 is installed on the output shaft of the drive mechanism 53. Please see Figure 3As shown, the air intake mechanism 5 can increase the air flow rate inside and outside the outer casing 2. The drive mechanism 53 drives the fan blades 52 to rotate, drawing outside air into the outer casing 2. The drive mechanism 53 is a variable frequency motor, and the output power of the drive mechanism 53 can be adjusted by the control mechanism 10 according to the temperature measured by the temperature sensor 9.

[0022] Please see Figures 1 to 3 As shown, the first filter mechanism 6 includes a filter housing 61 connected to the outer shell 51, a filter cotton 62 is provided inside the filter housing 61, and a cover 63 is installed on the outer end of the filter housing 61. The second filter mechanism 7 includes a filter housing 71 connected to the outer end of the exhaust port 24, a filter cotton 72 is installed inside the filter housing 71, and a cover 73 is installed on the outer end of the filter housing 71. In this utility model, the filter mechanism 6 and the filter mechanism 7 have the same structure. The air entering the outer cover 2 is first filtered by the filter cotton 62 in the filter housing 61 to prevent dust particles from entering the outer cover 2. The cover 63 serves as a fixing structure for the filter cotton 62. It has threads on its outer side and is fixed by screwing it onto the filter housing 61. The filter mechanism 2 7 is to prevent foreign objects from entering the outer cover 2 through the exhaust port 24. Similarly, the filter cotton 1 62 plays a filtering role, and the outer side of the cover 2 73 is also provided with threads, which are fixed to the filter housing 2 71 by screwing the threads. Both the cover 1 63 and the cover 2 73 are provided with ventilation holes.

[0023] An alarm mechanism 91 is installed on the outer side of the outer casing 2. The alarm mechanism 91 includes an audible alarm unit and a light alarm unit. The purpose of setting up the alarm mechanism 91 is to issue an audible and visual alarm when the temperature or water level inside the outer casing 2 reaches the preset alarm value, so as to alert the staff to check in time. The alarm mechanism 91 is controlled by the control mechanism 10.

[0024] The control mechanism 10 includes a signal analysis unit and a signal transmission unit, and the signal transmission unit includes a wired transmission module and a 4G transmission module; The control mechanism 10 can analyze the detection information of the water level sensor 8 and the temperature sensor 9, and can control and adjust the drive mechanism 53 (the adjustment and control of the above structure by the control mechanism 10 are all existing technologies, and will not be described in detail here). The control mechanism 10 can also connect to the control center via wired or wireless means, transmit signals to the control center, and control the equipment through the control center.

[0025] The working principle of this utility model is as follows: When installing the centrifugal pump body 4, the centrifugal pump body 4 is first fixedly installed on the base 1, and then the outer cover 2 is placed on the outside of the centrifugal pump body 4. During use, the air intake mechanism 5 draws outside air into the outer cover 2 through the air inlet 23 and exhausts it from the air outlet 24. The internal and external air flow carries away the heat generated by the centrifugal pump body 4 during operation, thereby achieving the purpose of heat dissipation for the centrifugal pump body 4. When outside air enters through the air inlet 23, it is first filtered by the filter mechanism 6 to prevent dust from entering the outer cover 2 and contaminating the centrifugal pump body 4, thus playing a protective role.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
