After briefly introducing the implementation principle of the present application, the following will clearly and completely describe the technical solution in the embodiments of the present application with reference to the drawings in the embodiments of the present application.
According to one aspect of the present application, there is provided a wind speed measurement device, as shown in fig. 1 and 2, comprising an anemometer, a mount 204, a flexible connecting strap and a locking assembly, for use in a scenario of measuring wind speeds at different heights on a lifting main arm 1.
The anemometer is configured to generate a wind speed signal. The anemometer may use an existing wind speed measuring device, and is mainly used to detect wind speed information at a mounting position of the anemometer to generate a wind speed signal.
The anemometer comprises a measuring body 201 and a mounting bracket 205, wherein the measuring body 201 is fixed on the mounting bracket 205 through screws, and the mounting bracket 205 is fixed on a mounting seat 204 through a plurality of screws. When the mounting bracket 205 is fixed on the mounting base 204, the existing fixing connection method, such as welding, clamping, and screwing, can be adopted.
The mounting seat 204 is fixedly arranged on the flexible connecting belt, and the flexible connecting belt is a flexible connecting belt. By arranging the flexible connecting band to be a flexible structure, when the flexible connecting band is fixed on the main lifting arm 1, the flexible connecting band can be more easily attached to each outer side surface of the main lifting arm 1 through self deformation. Therefore, the situation that the flexible connecting band of the wind speed measuring device can only be installed on the main lifting arm 1 with a certain specified cross section shape in an adaptive mode can be avoided, and therefore the wind speed measuring device in the embodiment can be smoothly installed on a plurality of groups of knuckle arms with different cross section shapes, and the adaptability is high.
In addition, the flexible connecting belt in the implementation is simple in form and structure and low in manufacturing cost, so that multiple groups of flexible connecting belts with different lengths can be configured for one group of wind speed measuring devices, and the flexible connecting belts with corresponding lengths can be selected as required to be fixedly installed. Moreover, the mounting base 204 and the mounting bracket 205 are detachably connected, so that the anemometer can be conveniently and quickly mounted on different mounting bases 204. Therefore, a foundation is provided for quickly connecting the same anemoscope with flexible connecting belts with different lengths.
A locking assembly is connected between the two ends of the flexible connecting band, the locking assembly being configured to connect the two ends of the flexible connecting band together. The locking components are fixedly connected with two ends of the flexible connecting band respectively, so that the flexible connecting band and the locking parts can form a closed ring together, and the wind speed measuring device is further fixed on the main lifting arm 1. Meanwhile, when the flexible connecting band is fixed to the outer side surface of the main lifting arm 1 having different circumferences, the distance between the two end portions of the flexible connecting band can be changed by the locking assembly, so that the circumference of the inner circle of the ring enclosed by the flexible connecting band and the locking assembly can be changed, and the purpose of fixing the flexible connecting band at different heights of the main lifting arm 1 can be achieved.
As shown in fig. 7 and 8, the main lifting arm 1 is mainly composed of a plurality of sets of jointed arms which are sequentially sleeved with each other, the sectional shapes of each set of jointed arms are different, and the circumferences of the outer side walls of each set of jointed arms are different, so that to realize that the wind speed measuring device is fixed on different heights of the main lifting arm 1 to monitor wind speed information on different heights, the flexible connecting band needs to be smoothly fixed on each jointed arm. The flexible connecting belt is fixed on the joint arms with different outer side wall circumferences by arranging the flexible connecting belt as the flexible connecting belt and adjusting the distance between two end parts of the flexible connecting belt through the locking parts. In addition, the flexible connecting belt is made of flexible materials, so that the flexible connecting belt can be better attached to the arms with different cross-sectional shapes.
In one possible implementation manner of the present application, as shown in fig. 2 and 3, the flexible connecting band includes a connecting band body 202 and two fixing portions 203.
The two fixing portions 203 are respectively disposed at two ends of the connecting band body 202, and the fixing portions 203 extend along a direction perpendicular to the connecting band body 202, in fig. 3, the X direction is an extending direction of the fixing portions 203, the Y direction is an extending direction of the connecting band body 202, a plurality of sets of connecting through holes 207 are disposed on the fixing portions 203, and the connecting through holes 207 on the two fixing portions 203 are both used for connecting with a locking component. Wherein, the two fixing parts 203 are two ends of the flexible connecting belt.
In one possible implementation of the present application, as shown in fig. 1 and 8, the locking assembly includes a connection screw 206 and a lock nut.
The connecting screws 206 are respectively and sequentially inserted into the connecting through holes 207 of the two fixing portions 203, and the locking nuts are screwed on the tail ends of the connecting screws 206. At this time, the two sets of fixing portions 203 are located between the head of the coupling screw 206 and the lock nut, and the distance between the two sets of fixing portions 203 can be changed by adjusting the distance between the lock nut and the head of the coupling screw 206. Thereby, the size of the loop enclosed by the flexible connecting band and the locking assembly can be adjusted.
In a possible implementation manner of the present application, the flexible connecting band further includes a reinforcing component, and the reinforcing component is fixedly connected to the connecting band body 202 and the fixing portion 203 respectively. By providing the reinforcing members, both end portions of the flexible connecting band can be reinforced, thereby preventing the fixing portion 203 from being deformed due to too large locking force of the locking member or preventing the connection between the fixing portion 203 and the flexible connecting band from being deformed or broken in the later mounting process. The safety of the fixed equipment is guaranteed, and the service life of the flexible connecting belt is prolonged.
Optionally, as shown in fig. 2 and 3, the reinforcing assembly includes a reinforcing plate 301.
The direction of longitudinal extension of the reinforcing plate 301, i.e., the X direction in fig. 3, is perpendicular to the direction of longitudinal extension of the flexible connecting strip, i.e., the Y direction in the figure.

The second reinforcing surface 304 is fixedly connected to the connecting band body 202. The first reinforcing surface 303 and the second reinforcing surface 304 form an angle which is the same as the angle formed between the fixing portion 203 and the connecting belt body 202. With this arrangement, deformation occurring at the joint of the fixing portion 203 and the connection band body 202 can be reduced.
Optionally, as shown in fig. 2, the reinforcing assembly further includes at least one reinforcing rib 302, and a plurality of sets of reinforcing ribs 302 are connected between the first reinforcing surface 303 and the second reinforcing surface 304 to further enhance the connection strength between the first reinforcing surface 303 and the second reinforcing surface 304.
In a possible implementation manner of the present application, the rubber pad is further included. The rubber pad is fixedly arranged on one side of the flexible connecting belt close to the main lifting arm 1. Therefore, when the flexible connecting band is fixed on the outer side wall of the main lifting arm 1, the probability that the flexible connecting band scratches the outer side surface of the main lifting arm 1 can be reduced.
Alternatively, as shown in fig. 1 and 2, the flexible connecting belt is a flexible steel belt, and the flexible steel belt can be bent and deformed in a direction perpendicular to the extending direction of the length of the flexible connecting belt, that is, in a direction perpendicular to the inner side and the outer side of the flexible connecting belt. Therefore, when the flexible connecting belt is fixedly sleeved on the outer side faces of the section arms, the inner side faces of the flexible connecting belt can be better attached to the outer side faces of the section arms through bending deformation of the flexible steel belt. Due to the flexibility of the flexible steel belt, the flexible connecting belt can be fixed on the arm sections with different cross-sectional shapes in a more fitting manner. Thereby improving the adaptability of the flexible connecting band and enabling the flexible connecting band to be more easily fixed to different positions of the main lifting arm 1.
