Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example: Refer to Figures 1-3 A tower crane mounting device for a rain gauge includes a rain gauge 3, with a water receiving hopper 4 at the top of the rain gauge 3, and further includes: At least one pair of support plates 1 are configured to be welded to the side wall of the tower crane. A groove is provided on the side of the support plate 1 away from the tower crane, and the rain gauge 3 is fixedly fitted into the groove. Rotating rod 2 is rotatably fixed inside water receiving hopper 4. A guide is provided on rotating rod 2. When rotating rod 2 rotates, the guide can generate a guiding force from inside water receiving hopper 4 to outside. The end of the connecting rod 5 and the rotating rod 2 away from the water receiving hopper 4 is fixed relative to the connecting rod 5 in a rotatable manner, and the end of the connecting rod 5 away from the rotating rod 2 extends along the direction of the support plate 1; A fastener is provided on the support plate 1. The fastener has a switchable connected or disconnected state. When the fastener is in the connected state, the connecting rod 5 is fixed relative to the support plate 1 through the fastener. When the fastener is in the disconnected state, the connecting rod 5 is slidably connected to the support plate 1.

[0018] This invention improves the stability of rain gauge 3 by setting at least one pair of support plates 1 and fixing the rain gauge 3 vertically through grooves. The support plates 1 are welded to the tower crane. One end of a rotating rod 2 is rotatably fixed inside the water collection hopper 4. A guide is provided on the rotating rod 2. During the rotation of the rotating rod 2, the guide generates a guiding force, which acts from inside the water collection hopper 4 outward. This helps to remove impurities such as fallen leaves and flying stones from the water collection hopper 4 during the use of the rain gauge 3, further improving the measurement accuracy of the rain gauge 3. In addition, one end of the rotating rod 2 is rotatably fixed to a connecting rod 5, which is fixed to the support plate 1 through a fixing rod 14. Based on the direct fixation of the rain gauge 3 to the support plate 1, a secondary fixation of the rain gauge 3 relative to the support plate 1 is achieved, improving the fixation strength and ensuring the stability of the rain gauge 3 under severe weather conditions.

[0019] Furthermore, it also includes: The first sliding bearing 6 is arranged between the rotating rod 2 and the water receiving hopper 4. The two ends of the first sliding bearing 6 are fixed to the screen plate 8 fixedly connected to the rotating rod 2 and the water receiving hopper 4, respectively. The second sliding bearing 7 has an adapter 9 fixedly connected to one end of the connecting rod 5 near the rotating rod 2. The adapter 9 has an annular structure, and the two ends of the second sliding bearing 7 are fixed to the adapter 9 and the rotating rod 2, respectively.

[0020] By installing a first sliding bearing 6 and a second sliding bearing 7 at both ends of the rotating rod 2, the first sliding bearing 6 is fixed to the water receiving hopper 4, and the second sliding bearing 7 is fixed to the connecting rod 5, thereby achieving the connection and fixation between the rain gauge 3 and the connecting rod 5 by the rotating rod 2.

[0021] Understandably, the bottom of the water receiving hopper 4 is fixedly connected to a sieve plate 8, which is used to drain rainwater and block impurities. By fixing the bottom of the first sliding bearing 6 to the sieve plate 8, the rotating rod 2 is fixedly rotatable relative to the water receiving hopper 4.

[0022] Furthermore, it also includes: A pair of buckles 10 are arranged opposite each other on both sides of the groove. One end of the buckle 10 is welded to the support plate 1, and the other end of the buckle 10 is welded to the connecting plate 11. The two connecting plates 11 on the pair of buckles 10 are fixed by bolts 12. The first pad 13 is fixed to the inner wall of the groove and is configured such that when a pair of retaining rings 10 are engaged, the first pad 13 abuts against the rain gauge 3.

[0023] By welding a pair of retaining rings 10 to each side of the groove, and welding a connecting plate 11 to the end of the retaining ring 10 away from the support plate 1, the two connecting plates 11 are connected and fixed by bolts 12 passing through the two corresponding connecting plates 11, thereby fixing the rain gauge 3 with a pair of retaining rings 10. In addition, the first pad 13 fixed in the groove abuts against the rain gauge 3, improving the connection stability between the rain gauge 3 and the support plate 1, and buffering the rain gauge 3 to ensure its measurement effect.

[0024] Furthermore, the fasteners include: The fixed rod 14 is distributed in the vertical direction and its side wall is fixedly connected to the connecting rod 5. The support plate 1 has a slot, and the fixed rod 14 passes through the slot and slides in cooperation with the support plate 1. A fixing mechanism is provided in the slot. The fixing mechanism has two fixing ends arranged opposite each other. The fixing ends are configured such that when the fixing rod 14 is fixed to the support plate 1, an external force can be generated between the two fixing ends in the direction of mutual approach, and the fixing ends and the fixing rod 14 have an elastic tendency in the direction of mutual distance, wherein the elastic tendency is less than the external force.

[0025] By fixing the fixing rod 14 to the connecting rod 5 and inserting the fixing rod 14 into the slot opened on the support plate 1, the fixing end of the fixing mechanism is used to fix and control the fixing rod 14. When the fixing ends are close to each other, the fixing rod 14 is fixed to the support plate 1, thereby achieving secondary fixing of the rain gauge 3 to the support plate 1. At the same time, in addition to the mutual external force between the fixing ends, there is also an elastic support force between the fixing ends and the fixing rod 14. Thus, while fixing the fixing rod 14, it also provides a vibration damping and buffering effect, further improving the stability of the rain gauge 3.

[0026] In one embodiment of the present invention, a block 27 is fixedly connected to the fixing rod 14, wherein when the fixing rod 14 is fixedly connected to the support plate 1, the edge of the slot of the uppermost support plate 1 is engaged with the block 27.

[0027] Furthermore, the fixed mechanism includes: A pair of card plates 15, with card slots provided on the adjacent sides of the pair of card plates 15, and the end of the fixing rod 14 extending into the empty slot is slidably engaged in the card slot; The second pad 16 is arranged in the slot and is elastically connected to the inner wall of the adjacent slot. When the fixing rod 14 is fixed relative to the support plate 1, the second pad 16 abuts against the fixing rod 14. A plurality of permanent magnets 18 are provided and fixedly attached to the adjacent sides of a pair of card plates 15 respectively, and are configured such that when the pair of card plates 15 are close to each other, the permanent magnets 18 located on the pair of card plates 15 generate an attractive force between them. The control unit is mounted on the support plate 1. The control unit has a control terminal connected to the adjacent card plate 15. The pair of card plates 15 move closer or further apart through the control unit.

[0028] By setting a pair of locking plates 15 to slide in the slot, the control unit controls the pair of locking plates 15 to move them closer or further apart. After the pair of locking plates 15 move closer together, the slot clamps the fixing rod 14 onto the support plate 1. At the same time, the second pad 16 is supported by the spring plate 17 and can abut against the fixing rod 14. Meanwhile, the permanent magnets 18 on the locking plates 15 generate an attractive force between them, thereby stably fixing the fixing rod 14 onto the support plate 1.

[0029] Furthermore, the control unit includes: A pair of screws 19 are rotatably fitted on both sides of the support plate 1. One end of the screw 19 extends into the empty groove and is threaded with a sleeve 21. The end of the sleeve 21 away from the screw 19 is fixedly connected to the adjacent clamping plate 15. A support ring 20 is provided around one end of the screw 19 that extends into the support plate 1, and the screw 19 and the support ring 20 are in sliding contact. The throttle 22 is fixed to the end of the screw 19 away from the clamping plate 15.

[0030] Rotating the screw 19 by the throttle 22 causes the sleeve 21 and the clamping plate 15 to be relatively fixed during rotation, thereby allowing the clamping plate 15 to slide along the slot. The clamping of the fixed rod 14 is achieved by the cooperation of a pair of clamping plates 15. In addition, the permanent magnet 18 is used to make the pair of clamping plates 15 attract each other, thereby effectively ensuring the relative stability between the screw 19 and the support plate 1 during the use of the rain gauge 3, and avoiding the reduction of the clamping strength of the clamping plate 15 on the fixed rod 14 due to the rotation between the screw 19 and the support plate 1.

[0031] Furthermore, the guide components include: Several guide plates 23 are fixedly connected to the outer periphery of the rotating rod 2 along the axial direction. The guide plates 23 extend into the water receiving hopper 4 and are rotatably fitted inside the water receiving hopper 4.

[0032] Furthermore, it also includes: The top end of the drive rod 24 and the rotating rod 2 extends vertically, and the bottom end of the drive rod 24 is fixedly connected to the top end of the rotating rod 2. The wind turbine 25 is fixedly connected to the top of the drive rod 24.

[0033] Furthermore, a welding plate 26 is welded to the end of the support plate 1 away from the groove. The welding plate 26 is used for welding and fixing to the tower crane.

[0034] By extending the top of the rotating rod 2 out of the second sliding bearing 7, and by fixing the shaft of the wind turbine 25 to the drive rod 24, while the drive rod 24 is fixed to the rotating rod 2, under the action of wind, the wind turbine 25 drives the drive rod 24 to rotate the rotating rod 2, and the rotating rod 2 drives several guide plates 23 to rotate, thereby discharging fallen leaves and other debris from the water collection hopper 4, ensuring the measurement effect of the rain gauge 3, and without the need for an external drive structure, reducing energy consumption.

[0035] The working process of this embodiment is as follows: By welding a pair of retaining rings 10 to each side of the groove, and welding a connecting plate 11 to the end of the retaining rings 10 away from the support plate 1, the two connecting plates 11 are connected and fixed by bolts 12 passing through them. This allows the pair of retaining rings 10 to clamp the rain gauge 3. A first sliding bearing 6 and a second sliding bearing 7 are installed at both ends of the rotating rod 2. The first sliding bearing 6 is fixed to the water receiving hopper 4, and the second sliding bearing 7 is fixed to the connecting rod 5. This connects and fixes the rain gauge 3 to the connecting rod 5. A fixing rod 14 is then fixed to the connecting rod 5 and inserted into a slot in the support plate 1. The fixing rod 14 is fixed by the fixing end of the fixing mechanism. When the fixing ends are close to each other, the fixing rod 14 is fixed to the support plate 1, realizing the secondary fixing of the rain gauge 3 to the support plate 1. The screw 19 is rotated by the throttle 22. During the rotation of the screw 19, the sleeve 21 and the clamping plate 15 are relatively fixed, so that the clamping plate 15 slides along the slot. The clamping of the fixing rod 14 is achieved by the cooperation of a pair of clamping plates 15. During use, the wind force causes the wind turbine 25 to rotate. The wind turbine 25 drives the drive rod 24 to rotate the rotating rod 2. The rotating rod 2 drives several guide plates 23 to rotate, thereby discharging fallen leaves and other debris from the water collection hopper 4 and ensuring the measurement effect of the rain gauge 3.
