Description

Technical Field

[0001] This utility model belongs to the field of marine wave buoy measurement and verification technology, specifically relating to a special fixing clamp for a spherical wave buoy verification device. Background Technology

[0002] The ocean covers approximately seven-tenths of the Earth's surface and is a vital component of the global ecosystem. Waves are one of the six major elements of ocean hydrology. The accuracy of ocean wave buoy data and information is of paramount importance for marine engineering construction, marine scientific research, marine data monitoring, and maritime transportation.

[0003] Existing marine buoy calibration devices generally fall into two categories. One type consists of two annular frames with four radially adjusting screws, each equipped with a locking block, evenly distributed on the frames. These screws clamp the buoy. However, measuring buoys that are too large or too small requires replacing the annular frames with those of the corresponding size. Furthermore, the clamping blocks deform and experience uneven stress during clamping, resulting in shortcomings in stability, convenience, and accuracy. The other type is a special clamp for wave buoys, which aligns the center of the clamped buoy with the height axis of the clamp, ensuring testing accuracy. However, this clamp requires numerous accessories and multiple pressure plates of different sizes, consuming significant manpower and time during clamping adjustments, and cannot handle excessively heavy wave buoys.

[0004] To address this issue, those skilled in the art have proposed a special fixing clamp for spherical wave buoy devices to solve the problems mentioned in the background art.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this novel experimental design, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide a special fixing fixture for a spherical wave buoy calibration device, so as to solve the problems of traditional fixtures requiring a large number of accessories and multiple pressure plates of different sizes, consuming a lot of manpower and time during adjustment and clamping, and being unable to clamp wave buoys with excessive weight.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A special fixing clamp for a spherical wave buoy calibration device includes:

[0009] The placement mechanism includes a clamp holder, a through hole is provided on the lower surface of the clamp holder, a support rod is inserted into the through hole, a tray is connected to one end of the support rod, the tray includes a receiving groove, a spherical buoy is placed in the receiving groove, and clamp holder pins are provided at both ends of the clamp holder.

[0010] The clamping mechanism includes a base plate fixedly installed on the periphery of the clamp holder, a bearing support installed on the base plate, a sliding bearing provided on the bearing support, a worm gear sleeved on the sliding bearing, and a plurality of worm wheels movably installed on the clamp holder. The worm wheels are driven by the worm gear, and grippers are connected to the worm wheels.

[0011] Preferably, the number and position of the worm gears are adapted to the worm, and the grippers are engaged with the circumferential side of the spherical buoy.

[0012] Preferably, a small handwheel is fixedly connected to one end of the worm gear.

[0013] Preferably, a fixing baffle is fixedly installed on the lower surface and the inner lower surface of the clamp holder, and the fixing baffle is provided with screw holes.

[0014] Preferably, the support rod is threadedly engaged with the fixed baffle through a screw hole, and a large handwheel is connected to the end of the support rod away from the tray.

[0015] Preferably, a large nut is screwed onto the circumferential side of one end of the support rod, and the large nut is in a compression fit with the fixed baffle.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model sets up a clamp holder with a tray and jaws. Using the approximately spherical thin shell-shaped clamp holder, the support height of the tray can be adjusted by rotating the large handwheel according to the scale on the support shaft, with the buoy diameter as the reference. The spherical buoy is placed in the bowl-shaped tray. The bowl-shaped structure can automatically center the spherical buoy by gravity. At this time, rotating the small handwheel drives the worm gear and worm wheel to cooperate, thereby driving the pair of jaws to move relative to each other inside the clamp, thereby clamping the spherical buoy.

[0018] (2) This utility model can realize the automatic centering and positioning of the spherical buoy, and use the transmission self-locking function of the worm gear and worm to make it clamped stably. At the same time, the bottom of the spherical buoy is supported by the liftable tray to disperse the weight of the spherical buoy. It can clamp heavy wave buoys, so that the clamping force on the buoy is smaller, which can protect the wave buoy and improve the reliability of positioning and clamping.

[0025] Example 1:

[0026] Please see Figures 1-3 As shown, a special fixing clamp for a spherical wave buoy calibration device includes:

[0027] The placement mechanism includes a clamp holder 2. A through hole is provided on the lower surface of the clamp holder 2. A support rod 11 is inserted into the through hole. One end of the support rod 11 is connected to a tray 10. The tray 10 includes a receiving groove. A spherical buoy 15 is placed in the receiving groove. A clamp holder pin 1 is provided at both ends of the clamp holder 2.

[0028] The clamping mechanism includes a base plate 3 fixedly installed on the periphery of the clamp holder 2, a bearing support 4 installed on the base plate 3, a sliding bearing 7 installed on the bearing support 4, a worm gear 6 sleeved on the sliding bearing 7, and a plurality of worm wheels 5 movably installed on the clamp holder 2. The worm wheels 5 are in transmission cooperation with the worm gear 6, and the worm wheels 5 are connected to the grippers 9.

[0029] Specifically, the number and position of the worm gears 5 are adapted to the worm 6, and the grippers 9 are engaged with the circumferential side of the spherical buoy 15.

[0030] Specifically, a small handwheel 8 is fixedly connected to one end of the worm gear 6.

[0031] Specifically, a fixing baffle 12 is fixedly installed on the lower surface and the inner lower surface of the clamp holder 2, and the fixing baffle 12 is provided with screw holes.

[0032] Specifically, the support rod 11 is threadedly engaged with the fixed baffle 12 through a screw hole, and a large handwheel 14 is connected to the end of the support rod 11 away from the tray 10.

[0033] Specifically, a large nut 13 is screwed onto the circumferential side of one end of the support rod 11, and the large nut 13 is pressed into the fixed baffle 12.

[0034] As can be seen from the above, this utility model, by setting up a clamp holder 2 with a tray 10 and grippers 9, utilizes the approximately spherical thin-shell-shaped clamp holder 2. Using the buoy diameter as a reference, the support height of the tray 10 can be adjusted by rotating the large handwheel 14 according to the scale on the support shaft. The spherical buoy 15 is placed in the bowl-shaped tray 10. The bowl-shaped structure allows the spherical buoy 15 to automatically center itself using gravity. At this time, rotating the small handwheel 8 drives the worm gear 6 and worm wheel 5 to engage in transmission, thereby driving the paired... The gripper 9 moves relative to the inside of the clamp to clamp the spherical buoy 15. This device can achieve automatic centering and positioning of the spherical buoy 15, and uses the transmission self-locking function of the worm gear 5 and worm 6 to make its clamping stable. At the same time, the liftable tray 10 supports the bottom of the spherical buoy 15 to distribute the weight of the spherical buoy 15. It can clamp heavy wave buoys, so that the clamping force on the buoy is smaller, which can protect the wave buoy and improve the reliability of positioning and clamping.
