[0036] Referring to Figure 1 and Figure 2 One end of any connecting rod 13 is detachably connected to the upper frame body 11, and the other end is detachably connected to the lower frame body 12, in the embodiment, the top of any connecting rod 13 is welded with a support plate 131 for supporting the upper frame body 11, any support plate 131 is in abutting cooperation with the lower surface of the upper frame body 11, any connecting rod 13 is rotatably connected to the lower frame body 12 through a rotating shaft, one side of the upper frame body 11 in the length direction is rotatably connected to two connecting rods 13 located on the same side through a rotating shaft, the other side of the upper frame body 11 is overlapped on the support plate 131 located on the same side, so that the connection between the upper frame body 11 and the connecting rod 13 is flexible and stable, facilitating the installation and dismounting of the upper frame body 11, the lower frame body 12 and the connecting rod 13 by the staff.

[0037] Referring to Figure 1 and Figure 2 The upper frame body 11 is symmetrically provided with a first lifting lug 111 and a second lifting lug 112, and the first lifting lug 111 and the second lifting lug 112 are both provided with two, so as to facilitate the staff to use hoisting equipment or manpower to carry the steel frame 1, accurately place the steel frame 1 to the predetermined position, reduce the difficulty of movement, and improve the work efficiency.

[0038] Referring to Figure 1 and Figure 2Any first lifting lug 111 is arranged on one side of the upper frame body 11 close to the rotating position, and any second lifting lug 112 is arranged on one side of the upper frame body 11 away from the rotating position. A limiting cylinder 113 is welded on the upper frame body 11 at a position corresponding to the first lifting lug 111.

[0039] With reference to Figure 1 and Figure 2 Since the structures and connection modes of the two first lifting lugs 111 are the same, one of the first lifting lugs 111 is taken as an example for illustration. The first lifting lug 111 is in the shape of a Chinese character 'jie', and one end of the first lifting lug 111 is integrally formed with a connecting ring 1111. The connecting ring 1111 is rotatably connected to the connecting rod 13 through a rotating shaft, that is, the first lifting lug 111 is coaxially rotatably connected to the upper frame body 11. The position of the first lifting lug 111 is fixed by a nut. The other end of the first lifting lug 111 is inserted into the limiting cylinder 113, thereby ensuring the stability of the position of the upper frame body 11 and the first lifting lug 111.

[0040] With reference to Figure 1 and Figure 2 Since the structures and connection modes of the two second lifting lugs 112 are the same, one of the second lifting lugs 112 is taken as an example for illustration. The second lifting lug 112 is in the shape of a U. One end of the second lifting lug 112 is rotatably connected to the connecting rod 13 and is limited in position by a nut. The other end of the second lifting lug 112 is sequentially arranged through the upper frame body 11 and the supporting plate 131 from top to bottom and is fixed by double nuts, so that the upper frame body 11 is stably arranged above the connecting rod 13.

[0041] With reference to Figure 1 and Figure 3 The upper frame body 11 is provided with a placing rack 114 and a protection cylinder 115 for placing the tide gauge. The placing rack 114 is integrally formed on the upper frame body 11. A square stepped hole 1141 is formed in the center of the placing rack 114, so that the protection cylinder 115 can be clamped in the stepped hole 1141 of the placing rack 114, preventing the protection cylinder 115 from shaking on the steel frame 1, further enhancing the stability of the tide gauge, and ensuring the accuracy and reliability of the measurement data.

[0042] With reference to Figure 4 A plurality of strip-shaped water inlet holes 1151 are circumferentially arranged on the side wall of the protection cylinder 115, ensuring the rapid balance of water flow inside and outside the protection cylinder 115, and ensuring the accuracy of the tide gauge in measuring the tidal level while not affecting the normal operation of the tide gauge.

[0043] With reference to Figure 4The protective cover 116 is detachably arranged on the protective cylinder 115. In the embodiment, the protective cover 116 is threadedly connected to the top of the protective cylinder 115, so that the sealing between the protective cover 116 and the protective cylinder 115 is ensured. The top of the protective cover 116 is welded with a pull ring 1161. The pull ring 1161 is arranged to facilitate the operator to twist and open the protective cover 116, thereby improving the convenience of operation.

[0044] With reference to Figure 1 and Figure 4 , the outer wall of the protective cylinder 115 is welded with a fixing plate 1152. In the embodiment, four fixing plates 1152 are circumferentially arranged. The lower frame body 12 is provided with support rods 121 for supporting the protective cylinder 115. The number of the support rods 121 corresponds to the number of the fixing plates 1152, and the support rods 121 are arranged at the four corners of the lower frame body 12. Since the structure and connection mode of the four support rods 121 are the same, one of the support rods 121 will be taken as an example for description.

[0045] With reference to Figure 5 and Figure 6 , the support rod 121 comprises a base rod 1211, a first abutting plate 1212 and a second abutting plate 1213. The first abutting plate 1212 is integrally formed at the upper end of the base rod 1211. The second abutting plate 1213 is rotatably connected to the lower end of the base rod 1211 through a rotating shaft.

[0046] With reference to Figure 4 and Figure 5 , the second connecting rod 13 is bolted to the lower frame body 12. The first abutting plate 1212 is bolted to the fixing plate 1152 on the outer wall of the protective cylinder 115, so that the contact area between the support rod 121 and the protective cylinder 115 is increased, and the connection stability between the support rod 121 and the protective cylinder 115 is further improved, thereby ensuring that the protective cylinder 115 can be stably fixed to the upper frame body 11 under water.

[0047] With reference to Figure 3 and Figure 6 , the lower frame body 12 is welded with clamping blocks 122 corresponding to the number of the base rods 1211. Any clamping block 122 is provided with a clamping groove 1221 for clamping cooperation with the base rod 1211. Since the support rod 121 is bolted to the lower frame body 12, when the support rod 121 is separated from the upper frame body 11, the worker can also adjust the placement angle of the base rod 1211 and the second abutting plate 1213 by loosening the bolt, so that the base rod 1211 is downwardly rotated to be clamped and fixed with the corresponding clamping groove 1221, thereby realizing the storage of the support rod 121.

[0048] The implementation principle of the embodiment of the application is as follows: in actual operation, first, the protection cylinder 115 is stably fixed and clamped in the stepped hole 1141 of the placing rack 114, then the tide gauge is placed in the protection cylinder 115, the protection cover 116 is screwed, the steel frame 1 is sunk to the designated position in the water through hoisting equipment, the protection cylinder 115 is kept vertically stable under the fixation of the steel frame 1 and the supporting rod 121, and effectively resists the impact of water flow, at this time, the water flow freely enters and exits the protection cylinder 115 through the water inlet hole 1151 and makes the water level in and outside the cylinder change synchronously, thereby ensuring that the tide gauge measures accurate data.

[0049] In the embodiment, the upper rack body 11 and the connecting rod 13 are connected in a rotating shaft rotating connection and lap joint mode, and the connecting rod 13 and the lower rack body 12 are connected in a rotating shaft rotating connection, so that the workers can easily realize the assembly and disassembly of the upper rack body 11, the lower rack body 12 and the connecting rod 13, the installation difficulty is reduced, and the installation efficiency is improved.

[0050] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
