They have high energy consumption and are not conducive to long-term use.
[0004] Based on this, the present invention designs a water tower cooling fan to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. Example
[0028] A water tower cooling fan includes a drive motor 1 and a water tower body 4. A PLC controller 2 is installed on the outer casing of the drive motor 1, and the PLC controller 2 is electrically connected to the drive motor 1. The PLC controller 2 is connected to an external display device and can monitor and adjust the actual working status of the drive motor 1. A fan blade 3 is fixedly connected to the output shaft of the drive motor 1. The drive motor 1 controls the fan blade 3 to rotate continuously and stably, thereby generating airflow to cool the water tower. Two sets of support columns 5 are fixedly connected between the two sides of the inner wall of the water tower body 4. The outer casing of the drive motor 1 is fixedly connected to the two sets of support columns 5 on both sides, which can support the drive motor 1. A temperature monitoring mechanism 6 is fixedly connected between the two sets of support columns 5.
[0029] Furthermore, the temperature monitoring mechanism 6 includes an outer frame 61, with both sides of the outer frame 61 fixedly connected to two sets of support columns 5. A monitoring channel 62 is provided inside the outer frame 61. A bottom seal 63 and a top seal 64 are rotatably connected to the bottom and top of the outer frame 61, respectively. The bottom seal 63 and top seal 64 can respectively seal the bottom and top of the monitoring channel 62. Therefore, when the water tower is not working or the fan's cooling efficiency is low, the monitoring channel 62 can be sealed, thereby reducing the continuous contact between the temperature sensor 68 and the external environment, improving its performance. The bottom seal 63... A connecting rod 65 is provided between the top of the bottom seal 63 and the bottom of the top seal 64. When the bottom seal 63 deflects at an angle, the connecting rod 65 can drive the top seal 64 to deflect in the same direction. A temperature sensor 68 is fixedly connected to the outer frame 61 and located on the inner wall of the monitoring channel 62. When the monitoring channel 62 is closed, it can indirectly monitor the temperature of the top of the water tower. When the monitoring channel 62 is open, it can directly monitor the temperature of the hot airflow, improving the accuracy of temperature monitoring. The temperature sensor 68 is electrically connected to the PLC controller 2 and can transmit the temperature monitoring data in real time.
[0030] Furthermore, a reset spring 67 is fixedly connected to the inner wall of the outer frame 61 and the monitoring channel 62. One end of the reset spring 67 is fixedly connected to the top of the bottom seal 63. A limiting block 69 for blocking the bottom seal 63 is also fixedly connected to the bottom of the outer frame 61, so that the bottom seal 63 will not leave the monitoring channel 62.
[0031] Furthermore, a contact block 66 is fixedly connected to one side of both the bottom seal 63 and the top seal 64. The contact block 66 is made of rubber and has a certain degree of elasticity, which improves the contact effect between the bottom seal 63, the top seal 64 and the side wall of the monitoring channel 62.
[0032] Furthermore, the top of the connecting rod 65 is rotatably connected to the bottom center of the top seal 64, and the bottom of the connecting rod 65 is rotatably connected to the top center of the bottom seal 63, enabling good transmission and facilitating synchronous and unidirectional deflection of the top seal 64 and the bottom seal 63. Figure 3 This is a diagram showing the result after deflection at a certain angle.
[0033] Furthermore, a protective net 7 is fixedly connected to the inner wall of the water tower body 4, the drive motor 1 is located above the protective net 7, and the fan blade 3 is located below the protective net 7.
[0034] The implementation principle of this embodiment is as follows: When the drive motor 1 is working, the airflow pushes the bottom seal 63 to deflect upward, and drives the top seal 64 to open the monitoring channel 62 simultaneously through the connecting rod 65. At this time, the temperature sensor 68 is in direct contact with the output airflow, which can more accurately collect data in real time and transmit it to the PLC controller 2. The PLC controller adjusts the speed of the drive motor 1 according to the preset program. When the water tower does not need to dissipate heat or stops working, the reset spring 67 pushes the bottom seal 63 to reset and close the channel, reducing the exposure time of the temperature sensor 68, avoiding the accumulation of dust and other impurities on the temperature sensor 68, and improving its service life.
[0035] Example 2: Refer to Figure 4 Based on Embodiment 1, the top of the connecting rod 65 is rotatably connected to the bottom middle position of the top seal 64, and the bottom of the connecting rod 65 is rotatably connected to the top middle position of the bottom seal 63, which allows the top seal 64 to deflect only a small angle after the bottom seal 63 deflects at a large angle, and vice versa, making it suitable for use in more environments.
