[0023] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. The components of the utility model embodiments described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Embodiment 1

[0025] A fan fixing device, comprising a base 5, a pair of mounting seats slidingly arranged on the base 5, and a driving mechanism for driving the pair of mounting seats to move towards or away from each other along the base 5.

[0026] The driving mechanism comprises a forward and reverse screw rod 4, and the pair of mounting seats are respectively threadedly connected with two threaded segments of the forward and reverse screw rod 4.

[0027] The mounting seat comprises a base plate 3 and a supporting plate 1 movably connected (such as hinged or shaft connected) with the base plate 3, and the fan is arranged between the two supporting plates 1.

[0028] Working principle: when the utility model is used, the fan is placed on the base 5, and then the forward and reverse screw rod 4 is rotated forward or reversely (specifically, the screw rod can be connected with a motor at one end, and the motor is used to drive the screw rod to rotate), which will drive the two mounting seats to move towards or away from each other along the base 5 simultaneously. When the two mounting seats move towards each other, that is, the two mounting seats approach each other, so that the supporting plates 1 of the two mounting seats can clamp the fan, which can maintain the fixing stability of the fan and can be suitable for clamping and fixing different models of fans, and the application range is wider.

[0029] When the fan is in the working process, vibration will occur, therefore, in the embodiment, a plurality of elastic supporting members 2 are arranged between the support plate 1 and the bottom plate 3, the elastic supporting member 2 comprises a pair of connecting rods 21 and a limiting spring 22 arranged on the pair of connecting rods 21; one end of the pair of connecting rods 21 is respectively hinged to the support plate 1 and the bottom plate 3; thus, when the vibration of the fan directly acts on the support plate 1, the elastic supporting member 2 can be used to elastically buffer the support plate 1, so that the support plate 1 can move with the vibration of the fan, thereby better adapting to the vibration generated in the use process of the fan and better avoiding the phenomenon that the fan is not stably installed due to the vibration in the use process.

[0030] In the embodiment, the first sliding groove 52 is arranged in the base 5, the forward and reverse screw rod 4 is arranged in the first sliding groove 52, the bottom surface of the bottom plate 3 is provided with the first sliding block 31, the first sliding block 31 is embedded in the first sliding groove 52, the first sliding block 31 is penetrated by the forward and reverse screw rod 4, and the first sliding block 31 is provided with an inner thread matched with the forward and reverse screw rod 4; a pair of second sliding grooves 51 are also arranged in the base 5, the second sliding grooves 51 are respectively and symmetrically arranged on the two sides of the first sliding groove 52, a positioning rod is arranged in each of the second sliding grooves 51, the bottom surface of the bottom plate 3 is provided with a pair of second sliding blocks 32, the second sliding blocks 32 are respectively and symmetrically arranged on the two sides of the first sliding block 31, and the positioning rod penetrates the second sliding block 32, and the second sliding block 32 can slide along the positioning rod.

[0031] Since the first sliding block 31 is embedded in the first sliding groove 52, and the second sliding block 32 is sleeved on the positioning rod on the two sides of the base 5, when the forward and reverse screw rod 4 rotates, the pair of first sliding blocks 31 can move relatively or oppositely along the forward and reverse screw rod 4, so that the two mounting seats move relatively or oppositely, and the fan is more stably clamped and held, thereby maintaining the stability of the fan.

[0032] In the embodiment, the inner side surface of the support plate 1 is provided with the anti-skid strip 11; thus, when the fan is placed between the two mounting seats, the inner side surface of the support plate 1 directly contacts the fan, so that the anti-skid strip 11 directly acts on the surface of the fan, thereby making the placement of the fan between the two support plates 1 more stable; further, the included angle between the support plate 1 and the bottom plate 3 is not more than 90 degrees, so that there is more clamping space, and the vibration in the working process of the fan can be better adapted; in addition, the support plate 1 can be arranged in an arc shape, so that the fitting degree with the outer side surface of the fan is higher, and the fan is more stably clamped.

[0033] In the embodiment, the power of the fan is 35-40kw, preferably 37kw, and an oil hole is formed in each of the two side end covers of the fan; the working load and temperature of the fan are reduced, the fan and the bearing are prevented from being burnt out, and the fan is more stable in use.

[0034] The above are only preferred embodiments of the present application and are not used to limit the present application, and for those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
