Description

Technical Field

[0001] The utility model relates to the technical field of motor installation, in particular to a motor installation base. Background Art

[0002] The mechanical ventilation cooling tower, also known as the mechanical ventilation cooling tower, is an important part of the cold end system of the power plant. It is mainly composed of fans, tower bodies, fillers, water collectors, etc. Compared with traditional natural ventilation cooling towers, mechanical ventilation cooling towers do not require tall wind tubes, so the design size can be reduced and the cost is relatively low. The mechanical ventilation cooling tower adopts the method of forced ventilation by fans. During operation, the air flow does not rely on the suction force produced by the air sealing difference inside and outside the tower, but is directly driven by the fan on the top of the tower. This ventilation method makes the cooling tower work more stable.

[0003] The fan of the cooling tower generally includes a wind wheel and a motor. The wind wheel is installed in the wind tube at the top of the tower, and the motor used to drive the wind wheel is installed on the top wall of the tower. As a key driving device, the working stability of the motor is particularly important. As an important structure supporting the motor, the design and manufacturing quality of the motor mounting base directly affect the stability and service life of the motor. The traditional motor mounting base is usually a flat plate structure. During installation, the flat plate structure is first installed on the bearing surface, and then the motor is fixed on the upper surface of the flat plate structure. The motor mounting base can meet the working requirements of short-term operation and low-power motors. However, for motors used in mechanical ventilation cooling towers, they have a long continuous working time and high power, and the motor generates a lot of heat. The traditional motor mounting base cannot dissipate the heat at the bottom of the motor in time, which can easily cause the motor to fail, thereby affecting the service life of the motor. At the same time, when the motor is repaired and replaced, the working efficiency of the mechanical ventilation cooling tower will also be reduced. Utility Model Content

[0010] Furthermore, two first grooves are provided on any one of the first side walls, two waist-shaped grooves are provided on any side of the installation plane, and one waist-shaped groove is correspondingly connected to one of the first grooves.

[0011] Furthermore, the portion between each two adjacent first grooves constitutes a support portion, which is a flat plate-like structure, and a thickness H of the support portion is smaller than a distance L1 from the mounting plane to the upper groove wall of the first groove and a distance L2 from the fixing plane to the lower groove wall of the first groove.

[0012] Furthermore, the second side wall is provided with convex edges on both upper and lower sides, and a reinforcing rib is provided between the two convex edges.

DETAILED DESCRIPTION

[0021] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0022] See also Figure 1-Figure 4The utility model provides a motor mounting base, including an integrally formed base body 1, the base body 1 including a mounting plane 11 for mounting the motor and a fixing plane 12 opposite to the mounting plane, a through longitudinal channel 101 is provided between the mounting plane 11 and the fixing plane 12, the side wall of the base body 1 located between the mounting plane 11 and the fixing plane 12 includes two oppositely arranged first side walls 13 and two oppositely arranged second side walls 14, a first groove 131 is provided on the first side wall 13, a second groove 141 is provided on the second side wall 14, a first opening 1311 is provided on the groove bottom wall of the first groove 131, a second opening 1411 is provided on the groove bottom wall of the second groove 141, the first opening 1311 and the second opening 1411 are both connected to the longitudinal channel 101, a waist-shaped groove 111 penetrating the first groove 131 is provided on the mounting plane 11, and a fixing foot 121 is convexly provided on the fixing plane 12.

[0023] The motor mounting base of the utility model is fixedly mounted on the top wall of the cooling tower by means of the fixing legs 121 during installation, and then the motor is fixedly mounted on the mounting plane 11 by means of the waist-shaped groove 111. When in use, due to the arrangement of the longitudinal channel 101, the bottom of the motor is suspended, thereby effectively preventing heat from accumulating at the bottom of the motor. At the same time, the first opening 1311 and the second opening 1411 are respectively arranged on the first side wall 13 and the second side wall 14, and are connected to the longitudinal channel 101, so that the two first side walls 13 and the two second side walls 14 are mutually connected, thereby facilitating the timely dissipation of the heat at the bottom of the motor through the surroundings of the base body 1. At the same time, natural wind can blow through the bottom of the motor, which is conducive to heat dissipation and reduces the situation where the motor fails due to overheating.

[0024] In addition, the first groove 131 that passes through the waist-shaped groove 111 provides an operable space for the fixing operation of the motor installed on the base through the waist-shaped groove 111, which greatly facilitates the user's installation operation. For example, the user can fix the motor on the base body 1 through a bolt. During the specific installation, after the lower end of the bolt passes through the waist-shaped groove 111 and extends to the first groove 131, the user can lock the nut on the lower end of the bolt in the first groove 131.

[0025] As a preferred embodiment, the upper opening of the longitudinal channel 101 is larger than the lower opening of the longitudinal channel 101. On the one hand, the larger opening of the longitudinal channel 101 located on the mounting plane 11 can reduce the shielding of the motor bottom by the mounting plane 11, which is beneficial to reduce the accumulation of heat at the motor bottom. On the other hand, the smaller opening of the longitudinal channel 101 located on the fixing plane 12 indirectly increases the contact area between the fixing plane 12 and the top wall of the cooling tower, which is beneficial to improve the installation stability of the base.

[0026] See also Figure 3, further, the channel side wall of the longitudinal channel 101 is set as a smooth transition slope. The smooth transition slope can avoid the longitudinal channel 101 having a protruding structure inside, which is more conducive to the natural wind passing through the bottom of the motor, effectively reducing the generation of turbulence, and helping to accelerate the heat dissipation of the motor. The angle between the channel wall of the longitudinal channel 101 and the longitudinal plane is α, where 5°≤α≤15°. In this embodiment, the angle α between the channel wall of the longitudinal channel 101 and the longitudinal plane is 10°.

[0027] As a preferred embodiment, two first grooves 131 are provided on any first side wall 13, and correspondingly, two waist-shaped grooves 111 are provided on any side of the mounting plane 11, and one waist-shaped groove 111 is correspondingly connected with one first groove 131. The provision of the waist-shaped grooves 111 can increase the flexibility of the base body 1, so that it can adapt to the installation needs of motors of different models and specifications, and has strong versatility in use.

[0028] Also, see Figure 1 , Figure 4 The portion between each two adjacent first grooves 131 constitutes a support portion 15, and the support portion 15 is a flat plate structure. The thickness H of the support portion 15 is smaller than the distance L1 between the mounting plane 11 and the upper groove wall of the first groove 131 and the distance L2 between the fixing plane 12 and the lower groove wall of the first groove 131. By providing the support portion 15, the size of the first groove 131 is increased while meeting the structural strength, thereby improving the heat dissipation effect.

[0029] Furthermore, the second side wall 14 is provided with protruding edges 142 on both upper and lower sides, and a reinforcing rib 143 is provided between the two protruding edges 142 . The provision of the reinforcing rib 143 can effectively improve the structural strength of the second side wall 14 and prevent the base body 1 from being easily deformed.

[0030] As a preferred embodiment, the length of the first side wall 13 is greater than that of the second side wall 14, the fixing legs 121 are correspondingly arranged on one side of the first side wall 13, and two fixing legs 121 are arranged on each side, and the fixing legs 121 are provided with fixing holes 1211, through which the user can use fasteners such as bolts or screws to fix the base body 1 on the top wall of the cooling tower. Furthermore, an auxiliary connection hole 144 is arranged on the lower groove wall of the second groove 141, and the auxiliary connection hole 144 is used to further fix the base body 1 on the top wall of the cooling tower through the above-mentioned fasteners, and the connection stability is strong.

[0031] In this embodiment, the base body 1 is made of ductile iron, which is integrally cast during processing without welding, which is convenient for processing and helps to control production costs.

[0032] The motor mounting base of the utility model is provided with a longitudinal channel 101 on the base body 1, which effectively avoids the problem of heat accumulation at the bottom of the motor, and a first opening 1311 and a second opening 1411 are provided on the first side wall 13 and the second side wall 14, so that the side walls of the base body 1 are in a through state, which is beneficial to the automatic dissipation of heat on the one hand, and is beneficial to the natural wind blowing through the bottom of the motor on the other hand, thereby enhancing the heat dissipation effect and reducing the possibility of motor failure due to overheating. At the same time, the first groove 131 which is connected with the waist-shaped groove 111 provides an operable space for the fixing operation of the motor installed on the base body 1 through the waist-shaped groove 111, which greatly facilitates the user's installation operation.

[0033] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description.
