Description

Technical Field

[0001] This utility model relates to a motor device, and more particularly to a heat dissipation monitoring motor device for a vacuum pump. Background Technology

[0002] Existing vacuum pump equipment primarily employs an integrated design, requiring a motor body to drive the corresponding functions. A connecting bracket is attached to the motor body to interface with the driven device. This design is relatively simple, lacking necessary external support and protection for the motor body, and it cannot achieve lubrication. The pre-coated lubricating oil can also splash and spill due to the impact of high-speed operation, affecting the cleanliness of the installation area.

[0003] Currently, some motors also employ a sheathed structure, which mainly involves enclosing the motor body with a spacer shell. However, this nested structure is prone to tolerance issues, leading to vibrations caused by improper friction in certain areas of the motor body. Furthermore, the overly sealed sides of this shell, while preventing some lubricant leakage, can cause localized heat buildup, affecting the motor's lifespan. Moreover, when heat buildup occurs, the current operating temperature cannot be detected, preventing timely adjustments to the motor's power and potentially causing drive malfunctions.

[0004] Meanwhile, the existing motor body is mainly installed by side-end docking, which cannot meet the needs of some lifting and hoisting operations, and additional brackets are required.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a heat dissipation monitoring motor device for vacuum pumps, making it more valuable for industrial applications. Utility Model Content

[0036] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0037] like Figure 1 A vacuum pump heat dissipation monitoring motor device includes a motor housing 5, within which a motor device 1 is installed. The key feature is that a junction box 2 is installed on the motor housing, and the junction box 2 contains pre-embedded terminals electrically connected to the corresponding drive terminals of the motor device 1. This allows for pre-planning of internal wiring; subsequent connection of drive control wires simply involves interfacing with the pre-embedded terminals, eliminating the need for secondary wiring of the motor device 1. This improves the installation efficiency of the motor device using this invention and avoids messy wiring, preventing wire runs during the motor device 1's operating stroke. Simultaneously, a sensing cavity is provided on the motor housing 5, within which a temperature sensor 3 is installed. This enables temperature monitoring during operation, ensuring the motor device 1 operates at a suitable temperature under stable conditions. In case of temperature control abnormalities, an alarm can be sent to the corresponding external device, meeting the temperature control monitoring requirements for long-term stable operation. For ease of implementation, the temperature sensor 3 can be a commercially available product of the corresponding model, which will not be elaborated further here.

[0038] Furthermore, to achieve passive heat dissipation during long-term operation, the motor housing 5 is equipped with several heat dissipation mechanisms 4, which allow the motor device 1 to exchange heat with the external environment, preventing heat accumulation and improving service life and operational stability. Moreover, to facilitate docking with subsequent motor equipment components and achieve stable assembly of this invention with better integration, the motor housing 5 is also equipped with connecting and positioning components.

[0039] According to a preferred embodiment of this utility model, the motor housing 5 is a split housing, including an upper housing and a lower housing, which enclose the motor device 1 to protect it. Simultaneously, fixed guide cylinders 6 are distributed along the outer edges of both the upper and lower housings, with cold-forged bolts 7 connected to the fixed guide cylinders 6. This allows for convenient bolt locking. Furthermore, the split housing design allows for adjustment of the actual position of the motor device 1 during assembly, reducing tolerances and preventing vibration during use. Moreover, several hanging guide posts 15 are distributed on the upper housing, with lifting lugs 16 connected to the hanging guide posts 15. This facilitates lifting and assembly; the lifting lugs 16 can be removed after installation. Additionally, the lifting lugs 16 can be retained for the lifting and operation needs of certain motor equipment, meeting different installation processes or requirements.

[0040] Looking further, junction box 2 includes a bakelite box body with pre-embedded terminals installed inside. Specifically, the pre-embedded terminals have copper guide posts, and the bakelite box body has wiring holes 8 at the corresponding positions of the pre-embedded terminals. Thus, after installation on the corresponding equipment, the pre-installed drive control wires of the equipment can be connected to the wiring holes 8 and aligned with the corresponding pre-embedded terminals to achieve connection with the motor device 1. Simultaneously, a cover is screwed onto the bakelite box body. This allows for effective locking after wiring is completed, preventing the entry of external foreign objects while improving insulation and enhancing wiring safety.

[0041] In practical implementation, the motor housing 5 is provided with several positioning holes 9 and wire holes 10 at the position corresponding to the sensing cavity. This allows the built-in temperature sensor 3 to be securely positioned by screws into the positioning holes 9, ensuring a stable connection even during normal impact vibrations during vacuum motor operation. This provides real-time temperature data during subsequent motor operation, enabling adjustments to the power of the motor device 1 and preventing overheating. Simultaneously, considering passive cooling, the heat dissipation mechanism 4 consists of several elongated oval heat dissipation holes arranged in an array at equal intervals. This increases the contact area between the built-in motor device 1 and the external environment while providing adequate spacing protection, improving the heat exchange efficiency required for passive cooling and achieving stable operation over extended periods. Furthermore, insect-proof nets can be attached inside the heat dissipation holes. For externally mounted motor devices, this provides excellent heat dissipation while effectively preventing the intrusion of external insects, without affecting the normal operation of the motor device 1.

[0042] Furthermore, the connecting and positioning component used in this invention is a fixing plate 11 installed on one side of the motor housing 5. The fixing plate 11 has extended fins, and each extended fin has a plurality of fixing holes 12. During implementation, the fixing holes 12 are preferably threaded holes, facilitating positioning with screws to install this invention into a predetermined placement space and achieve locking. Alternatively, a protruding post can be used for limiting, and the fixing holes 12 can be internal circular holes, which will not be elaborated further here.

[0043] Meanwhile, to withstand the lateral pressure impact that may occur due to air pressure changes during the operation of the motor device 1, several reinforcing ribs 13 are distributed on the motor housing 5. In this way, effective reinforcement of the joint end can be achieved, and stress impact can be withstood without abnormal deformation.

[0044] Furthermore, this utility model has several indicator nameplates 14 affixed to the motor housing 5. These nameplates can be installed at the locations of the temperature sensor 3 and the junction box 2 as needed, providing information such as the effective operating temperature range and wiring guidance, facilitating quick identification and installation by the user.

[0045] The working principle of this utility model is as follows:

[0046] The present invention is assembled with the motor equipment in a pre-defined manner, with the fixing plate 11 used for auxiliary positioning. After assembly, the corresponding wires are connected to the junction box 2 according to the nameplate guidance to realize the drive control of the motor device 1.

[0047] During operation, the operating temperature of motor 1 is collected by temperature sensor 3, which facilitates the corresponding power drive of the motor equipment's control components and prevents abnormal operating temperature. During this period, passive heat exchange with the external environment is achieved through heat dissipation mechanism 4 to cool the motor 1.

[0048] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0049] 1. It is equipped with a junction box for pre-wiring, which facilitates the connection of drive wires during assembly and meets the external insulation effect after connection, thereby improving the safety of use.

[0050] 2. It is equipped with a temperature sensor, which can monitor the actual operating temperature of the motor under suitable working conditions, avoid abnormal high-temperature operation, and, with the cooperation of external equipment, realize the injection of lubricating oil and cooling, thereby improving service life.

[0051] 3. It is equipped with a heat dissipation mechanism, which can achieve appropriate passive cooling and prevent heat accumulation in local areas.

[0052] 4. The motor unit has an independent motor housing, which provides effective external isolation protection.

[0053] 5. The motor housing adopts a split upper and lower structure, which facilitates the internal positioning of the motor device and reduces the impact of joint tolerances.

[0054] 6. Additional lifting lugs can be added as needed to meet the requirements of transportation hoisting or hoisting top connection.

[0055] 7. The overall structure is simple, making it easy to manufacture and use.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
