DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] like Figure 1-7 As shown, a floating tidal bore warning device comprises a plurality of combined guide sliding kits 2 equidistantly mounted on a column 1, the combined guide sliding kit 2 is a polyhedron, and a mounting plate 3 is fixedly mounted on each face, a combined connecting rod assembly 4 is movably arranged on the mounting plate 3, and a floating plate 5 which is perpendicular to the mounting plate 3 is mounted on the output end of the combined connecting rod assembly 4;

[0043] It also includes a pressure sensor 6, which is used to detect the force applied to the combined connecting rod assembly 4 when the floating plate 5 moves up and down with the rising tide.

[0044] Specifically, the column 1 in the embodiment may be a corrosion-resistant alloy part or a prefabricated concrete part, whichever is known to those skilled in the art.

[0045] The combined guide sliding kit 2 in the above embodiment can be a symmetrically arranged sliding member fixed by bolts, or a sliding plate with a mounting surface.

[0046] Furthermore, the combined connecting rod assembly 4 in the embodiment can be two sliding-fitting rods, or three sliding-fitting rods, or a plurality of sliding-fitting rods.

[0047] In the above technology, the floating plates 5 in the embodiment are installed along each surface of the combined guide sliding kit 2, so when the tide rises, there is always a floating plate 5 that is first subjected to force, and the floating plate 5 moves up, thereby switching the state of the combined connecting rod assembly 4, so that the pressure sensor 6 changes the force according to the detection state switching force, thereby judging the current tide change speed.

[0048] As an embodiment further provided by the present invention, the combined guide sliding kit 2 includes a symmetrically arranged U-shaped slot member 21 and an umbrella-shaped fixing member 24, and a T-shaped block 22 is centrally arranged on the inner wall of the U-shaped slot member 21 on the side opposite to the port;

[0049] The outer walls of the pillar 1 on opposite sides are provided with first grooves 11 for the T-block 22 to slide;

[0050] Guide rollers 23 are rotatably arranged on the inner sides of both ends of the U-shaped slot member 21, and the guide rollers 23 are located in the guide rail grooves 12 symmetrically opened on the outer wall of one side of the column 1 adjacent to the first groove 11;

[0051] The umbrella-shaped fixing member 24 has at least two first inclined surfaces 241, and the outer side surfaces at both ends of the U-shaped slot member 21 are provided with second inclined surfaces 211. The umbrella-shaped fixing member 24 is embedded between the two U-shaped slot members 21, and the first inclined surface 241 and the second inclined surface 211 are slidably connected to make the guide roller 23 slidably connected to the guide rail groove 12.

[0052] Specifically, in the embodiment, combined Figure 2 It can be seen that during installation, the U-shaped slot parts 21 are pre-clamped on both sides of the column 1, and then the umbrella-shaped fixing part 24 is embedded between the two U-shaped slot parts 21, and then bolts are passed through the umbrella-shaped fixing part 24 to connect with the U-shaped slot parts 21 respectively.

[0053] During installation, due to the sliding cooperation of the first inclined surface 241 and the second inclined surface 211, the U-shaped slot member 21 slides under the first inclined surface 241 and the second inclined surface 211 to separate, so that the guide roller 23 abuts against the guide rail groove 12 to form a barrier, thereby limiting the further separation of the two U-shaped slot members 21.

[0054] After installation, a plane for installing the installation plate 3 is formed between the umbrella-shaped fixing member 24 and the two U-shaped slot members 21 .

[0055] As another embodiment further provided by the present invention, the combined connecting rod assembly 4 includes:

[0056] A symmetrically arranged first connecting rod 41, a first end of which is rotatably connected to the mounting plate 3, and a second end of which is rotatably connected to a connecting group 57 fixedly installed on the back of the floating plate 5;

[0057] The symmetrically arranged second connecting rod 42 has a first end rotatably connected to the mounting plate 3 , and a second end slidably connected to the first waist groove 411 provided on the first connecting rod 41 .

[0058] Further, in the embodiment, when the floating plate 5 moves upward, the second connecting rod 42 slides in the first waist groove 411, and the second connecting rod 42 here can be pulled by a tension spring, or maintained by an equidistant spring located in the first waist groove 411, so that the combined connecting rod assembly 4 is maintained. Figure 1 status.

[0059] As another embodiment further provided by the present invention, the combined connecting rod assembly 4 includes a symmetrically arranged third connecting rod 43 , a first end of which is rotatably connected to the mounting plate 3 , and a second end of which is slidably connected to a second waist groove 421 provided on the second connecting rod 42 .

[0060] Specifically, the third connecting rod 43 in the embodiment slides in the second waist groove 421 opened on the second connecting rod 42, so when the floating board 5 floats and moves upward, the second connecting rod 42 slides in the first waist groove 411, and at the same time, the third connecting rod 43 slides in the second waist groove 421 opened on the second connecting rod 42, and the two share the force, so that the floating board 5 is subjected to the maximum force.

[0061] As another embodiment further provided by the present invention, the combined connecting rod assembly 4 includes a sleeve rod 44 rotatably arranged on the mounting plate 3, a piston rod 45 is slidably arranged in the sleeve rod 44, and the piston rod 45 is rotatably arranged on the third waist groove 431 opened on the third connecting rod 43;

[0062] A piston block 46 is provided at one end of the piston rod 45 located inside the sleeve rod 44 . The piston block 46 is centrally arranged inside the sleeve rod 44 , and the air pressure on both sides of the piston block 46 is the same. Stop springs 47 are provided at both ends of the piston block 46 .

[0063] Specifically, the embodiment uses the cooperation of air pressure and the resistance spring 47 to drive the piston rod 45 and the sleeve rod 44 to move inside. When the floating board 5 moves upward in the embodiment, the second connecting rod 42 slides in the first waist groove 411, and the third connecting rod 43 slides in the second waist groove 421 opened on the second connecting rod 42. Synchronously, as the third connecting rod 43 slides in the second waist groove 421, the piston rod 45 slides in the third waist groove 431, so that the length of the piston rod 45 and the sleeve rod 44 gradually decreases, that is, as the floating board 5 moves upward, the length decreases, thereby providing the floating board 5 with a damping force. By using the sliding cooperation of at least three waist grooves, the damping force provided to the floating board 5 is maximized.

[0064] As another embodiment further provided by the present invention, the floating plate 5 includes a main body 51 and an inner lining plate 52 fixedly arranged at the end interface of the main body 51;

[0065] The air pressure between the main body 51 and the inner lining plate 52 is uniform;

[0066] A core column 53 is centrally disposed inside the main body 51, and the core column 53 is fixedly connected to the inner lining plate 52;

[0067] The non-contact portion between the lining plate 52 and the core column 53 is a floating portion 521;

[0068] The inner wall of the main body 51 is provided with an elastic connecting arm 54 connected to the floating portion 521;

[0069] The pressure sensor 6 is arranged inside the main body 51 , with its detection surface facing the floating portion 521 .

[0070] Specifically, because the floating plate 5 is subjected to the damping force provided by the combined connecting rod assembly 4 during the floating process, the floating portion 521 of the floating plate 5 is depressed inwardly under the action of the hydraulic pressure during the floating process, and the pressure sensor 6 detects the change in internal pressure under the squeezing, thereby judging the speed of the current tide by the speed of the pressure change.

[0071] As another embodiment further provided by the present invention, a rough rubber ring 231 is fixedly provided on the outer wall of the guide roller 23, a rotating shaft 232 is fixedly installed on the guide roller 23, and a track gear disc 233 is fixedly installed on the rotating shaft 232;

[0072] Hook tongues 234 are respectively provided on the end sections of the guide roller 23 along the rectangular diagonal lines. In a default state, the four hook tongues 234 are meshed and locked with the track toothed disc 233 .

[0073] Furthermore, a synchronous wheel 2341 is fixedly installed on the hook tongue 234, and a tension control wheel 2342 is symmetrically rotatably arranged on the end section of the guide roller 23, and a synchronous belt 25 is sleeved on the four synchronous wheels 2341 and the two tension control wheels 2342.

[0074] Furthermore, a first trapezoidal gear 2343 fixedly mounted on the end surface of one of the synchronous wheels 2341 is transmission-connected with a second trapezoidal gear 441 fixedly mounted on the shaft of the sleeve rod 44 via a double-end trapezoidal gear member 48 .

[0075] Specifically, in the embodiment, when the combined connecting rod assembly 4 moves up to a predetermined height along with the floating plate 5, as the flipping angle of the combined connecting rod assembly 4 changes, the length of the piston rod 45 and the sleeve rod 44 will be driven to gradually decrease. At this time, the double-ended trapezoidal gear member 48 drives one of the synchronous wheels 2341 to rotate under the transmission of the second trapezoidal gear 441, thereby driving the four hook tongues 234 to rotate away from the track gear plate 233, thereby releasing the locking relationship. At this time, the guide roller 23 moves up synchronously with the floating plate 5.

[0076] It should be noted that the guide roller 23 in the embodiment is mounted on the mounting plate 3 .

[0077] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
