Description

Technical Field

[0001] This application relates to the field of water protection, and in particular to a wind-guiding and wind-proof device. Background Technology

[0002] The descriptions in this section provide background information related to this disclosure only and do not constitute prior art. Evaporation equipment typically needs to be installed on the water surface. Since evaporation equipment requires a certain amount of wind to assist evaporation, excessive wind volume necessitates protection to prevent damage. Existing windproof devices rely on manual shut-off, which is labor-intensive and inefficient. Summary of the Invention

[0003] In view of this, this application provides a wind deflector and windproof device that can automatically switch on and off, protect equipment from damage by strong winds, and reduce labor intensity.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A wind-guiding and wind-blocking device, characterized in that it includes a frame and multiple blade units connected to the frame. The frame is a square frame, and the blade units are spaced apart along the length of the frame. Each blade unit includes an elastic connector, a rotating shaft vertically arranged and rotatably connected to an upper and lower crossbar of the frame, a wind deflector fixedly connected to the rotating shaft and located in the frame, and a wind guide plate fixedly connected to the rotating shaft and located above the frame. The wind guide plate is a cantilever structure fixedly connected to the rotating shaft on one side, and the wind guide plate and the wind deflector are arranged at an angle. The elastic connector is connected between the frame and the wind guide plate to provide elastic force to the wind deflector, so that the wind deflector is in an open state in the initial state. When the wind force increases and pushes the wind guide plate to rotate, it can rotate the rotating shaft and the wind deflector together, so that the wind deflector partially or completely closes the opening in the middle of the frame.

[0006] The aforementioned wind-guiding and windproof device comprises multiple blade units arranged on a frame. When the air volume is low, the rotating shaft remains stationary under the action of the elastic connector, and the wind deflectors are open, allowing air to pass through the gaps between the wind deflectors and be blown into the aquatic equipment for its use. When the air volume reaches a certain level, the wind will blow the wind guide plates, causing them to push open the elastic connectors and rotate the rotating shaft. This reduces or completely closes the gaps between the wind deflectors, thereby protecting the equipment. Compared to manual operation, this device reduces labor intensity and improves work efficiency.

[0007] In some embodiments, the elastic connector is a torsion spring fitted around the outer periphery of the shaft.

[0008] In some embodiments, the blade unit further includes a reversing assembly, which includes a locking mechanism, a base fixedly mounted on the upper crossbar of the frame, and a rotating seat rotatably mounted on the base. Both the base and the rotating seat have through holes in their middle sections to facilitate the upward passage of the rotating shaft. The rotating seat also has a mounting groove for placing the torsion spring body. One end of the torsion spring's torque arm is connected to the rotating seat, and the other end's torque arm is connected to the wind guide plate. The rotating seat has a first state in its initial position and a second state rotated 180°. The locking mechanism can fix the rotating seat in either the first or second state. Because the wind direction differs between summer and winter, the rotating seat needs to be rotated 180° when the wind direction changes, allowing the torsion spring to be used in a different direction.

[0009] In some embodiments, the rotating base is provided with at least two oppositely arranged pin holes, and the locking mechanism is a pin structure that is fixedly installed on the base and can be inserted into the pin holes.

[0010] In some embodiments, the pin structure is a spring pin. This spring pin can automatically return to its original position when pulled out.

[0011] In some embodiments, the air guide plate includes a sleeve that can be fitted and fixed to the upper end of the rotating shaft and a plate body fixedly connected to the sleeve. A cap for preventing the sleeve from detaching upwards is also detachably fixed to the top of the rotating shaft. The air guide plate is a detachable structure for easy replacement and facilitates the installation of the base and rotating seat. Alternatively, the air guide plate can be directly welded to the rotating shaft.

[0012] In some embodiments, the upper outer periphery of the rotating seat is provided with rotating teeth, and a rack that can move along the length of the frame is slidably connected to the base. The rack meshes with the rotating teeth of each rotating seat for transmission. During linear movement, the rack can synchronously rotate the rotating seats. The locking mechanism is a pin or bolt that fixes the rack to the base or upper crossbar. Pulling the rack can drive multiple rotating seats to rotate together, thus enabling synchronous rotation and high working efficiency. The structure of multiple rotating seats linked together can also be a multi-link structure, etc.

[0013] In some embodiments, the wind deflector is a straight plate or an arc-shaped plate.

[0014] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0015] This application discloses a wind-guiding and windproof device. Multiple blade units are arranged on a frame. When the airflow is low, the rotating shaft remains stationary under the action of elastic connectors, and the wind deflectors are open. Air passes through the gaps between the wind deflectors and is blown into the aquatic equipment for its use. When the airflow reaches a certain level, the wind blows the wind guide plates, which push open the elastic connectors, causing the rotating shaft to rotate. This reduces or completely closes the gaps between the wind deflectors, thus protecting the equipment. Compared to manual operation, this reduces labor intensity and improves work efficiency.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0026] Example 1:

[0027] See Figures 1 to 7This application provides a wind-guiding and windproof device, including a frame 1 and multiple blade units connected to the frame 1. The frame 1 is a square frame, and the blade units are spaced apart along the length of the frame 1. Each blade unit includes an elastic connector, a rotating shaft 3 vertically arranged and rotatably connected to the upper crossbar 11 and lower crossbar 12 of the frame 1, a wind deflector 4 fixedly connected to the rotating shaft 3 and located in the frame 1, and a wind guide plate 5 fixedly connected to the rotating shaft 3 and located above the frame 1. The wind guide plate 5 is a cantilever structure fixedly connected to the rotating shaft 3 on one side, and the wind guide plate 5 and the wind deflector 4 are arranged at an angle. The elastic connector is connected between the frame 1 and the wind guide plate 5 to provide elastic force to the wind deflector 4, so that the wind deflector 4 is in an open state in the initial state. When the wind force increases and pushes the wind guide plate 5 to rotate, it can rotate the rotating shaft 3 and the wind deflector 4 together, so that the wind deflector 4 partially or completely closes the opening in the middle of the frame 1.

[0028] This wind-guiding and windproof device has multiple blade units on the frame 1. When the air volume is low, the rotating shaft 3 remains stationary under the action of the elastic connector, and the wind deflector 4 is open. The air passes through the gaps between the wind deflectors 4 and blows into the water equipment for its use. When the air volume reaches a certain level, the wind will blow the wind guide plate 5, which pushes open the elastic connector, causing the rotating shaft 3 to rotate. This reduces or completely closes the gaps between the wind deflectors 4, thus protecting the equipment. Compared with manual operation, this device reduces labor intensity and improves work efficiency.

[0029] The included angle between the air guide plate 5 and the wind baffle plate 4 is 70° to 90°.

[0030] The elastic connector is a torsion spring 2 that is sleeved on the outer circumference of the rotating shaft 3.

[0031] The blade unit also includes a reversing assembly, which includes a locking mechanism 8, a base 6 fixedly mounted on the upper crossbar 11 of the frame, and a rotating seat 7 rotatably mounted on the base 6. Both the base 6 and the rotating seat 7 have through holes in their middle sections to facilitate the upward passage of the rotating shaft 3. The rotating seat 7 also has a mounting groove 71 for placing the torsion spring body. One end of the torsion spring 2 is connected to the rotating seat 7, and the other end is connected to the wind guide plate 5. The rotating seat 7 has a first state in its initial position and a second state rotated 180°. The locking mechanism 8 can fix the rotating seat 7 in either the first or second state. Because the wind direction differs between summer and winter, when the wind direction changes, the rotating seat 7 needs to be rotated 180° to allow the torsion spring 2 to be used in a different direction.

[0032] The rotating base 7 is provided with at least two oppositely arranged pin holes 72, and the locking mechanism 8 is a pin structure that is fixedly installed on the base 6 and can be inserted into the pin holes 72.

[0033] The pin structure is a spring pin. This spring pin can automatically return to its original position when pulled out.

[0034] The air guide plate 5 includes a sleeve 51 that can be fitted and fixed to the upper end of the rotating shaft 3, and a plate 52 fixedly connected to the sleeve 51. A cover 9 is detachably fixed to the top of the rotating shaft 3 to prevent the sleeve 51 from detaching upwards. The air guide plate 5 is a detachable structure for easy replacement and to facilitate the installation of the base 6 and the rotating seat 7. Alternatively, the air guide plate 5 can be directly welded to the rotating shaft 3.

[0035] The wind deflector 4 is a straight plate or an arc plate.

[0036] The following is a brief description of the working process and usage method of the wind-guiding and windproof device described in the above embodiment:

[0037] See Figure 1 and Figure 7 When the airflow is low, the wind deflector 4 is at a certain angle relative to the frame 1, and the airflow is guided to the water equipment through the wind deflector 4. (See also...) Figure 2 When the airflow increases, it blows the air guide plate 5, which pushes open the elastic connector, causing the rotating shaft 3 to rotate. This reduces or completely closes the gaps between the wind deflectors 4, thus protecting the equipment. Because the wind direction differs in summer and winter, the torsion spring 2 needs to be reversed when the wind direction changes.

[0038] Example 2:

[0039] See Figure 8 The difference between this embodiment and the first embodiment described above is that: the upper outer periphery of the rotating seat 7 is provided with rotating teeth, and a rack 10 that can move along the length direction of the frame 1 is slidably connected to the base 6. The rack 10 meshes with the rotating teeth of each rotating seat 7 for transmission. During linear movement, the rack 10 can synchronously rotate the rotating seats 7. The locking mechanism 8 is a pin or bolt that fixes the rack 10 to the base 6 or the upper crossbar 11. Pulling the rack 10 can drive multiple rotating seats 7 to rotate together, so that the rotating seats 7 can rotate synchronously, resulting in high working efficiency. The structure of multiple rotating seats 7 linked together can also be a multi-link structure or a chain drive mechanism, etc.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
