[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0032] Please refer to Figure 1 , Figure 2 and Figure 4 , the folding telescopic water depth ruler in the embodiment comprises a first ruler body 1, a second ruler body 2, a third ruler body 3 and a fourth ruler body 4 are sequentially arranged above the first ruler body 1, wherein the left end of the first ruler body 1 is hingedly connected with the left end of the second ruler body 2, the right end of the second ruler body 2 is hingedly connected with the right end of the third ruler body 3, and the left end of the third ruler body 3 is hingedly connected with the left end of the fourth ruler body 4. Through the above arrangement, the folding purposes of the first ruler body 1, the second ruler body 2, the third ruler body 3 and the fourth ruler body 4 can be achieved, the storage space is effectively reduced, it is convenient to carry, and at the same time, the user can conveniently fold and turn over the corresponding number of ruler bodies according to the required length. The surfaces of the first ruler body 1, the second ruler body 2, the third ruler body 3 and the fourth ruler body 4 are all provided with scale lines 8, and through the arrangement of the scale lines 8, the user can conveniently observe.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 , the first ruler body 1, the second ruler body 2, the third ruler body 3 and the fourth ruler body 4 are all made of light high-strength aluminum alloy material, which not only has sufficient strength and hardness, can withstand certain underwater pressure and bending force during operation, but also is light in weight, convenient to carry and operate. At the same time, the aluminum alloy material has good corrosion resistance and can maintain stable performance in underwater environment for a long time. The first ruler body 1, the second ruler body 2, the third ruler body 3 and the fourth ruler body 4 are equal in length. The equal length design makes each ruler body maintain consistent length when folding and unfolding. The left end of the first ruler body 1 and the left and right ends of the third ruler body 3 are all fixedly connected with matching clamps 5, and the left and right ends of the second ruler body 2 and the left end of the fourth ruler body 4 are all fixedly connected with extrusion blocks 6. Through the turning over of the ruler bodies, the extrusion blocks 6 can enter the inside of the matching clamps 5, and then the extrusion blocks 6 and the matching clamps 5 are connected through interference fit, so as to ensure the perpendicularity. The cross section of each extrusion block 6 is trapezoidal, and through the arrangement of the trapezoidal cross section, the extrusion block 6 can enter the inside of the matching clamp 5.

[0034] Please refer toFigure 1 、 Figure 2 and Figure 3 The surfaces of the first ruler body 1, the second ruler body 2, the third ruler body 3 and the fourth ruler body 4 are fixedly embedded with water writing cloth 7. Through the arrangement of the water writing cloth 7, the water writing cloth 7 changes color when encountering water after the ruler body is inserted into water, so that the water level position can be conveniently judged. The right side surface of the fourth ruler body 4 is threadedly connected with a threaded column 9, and the other end of the threaded column 9 is fixedly connected with a counterweight ball 10. The counterweight ball 10 increases the gravity at the bottom end and ensures the verticality of the surveying ruler extending underwater, so as to ensure the accuracy of the surveying result. The right end of the first ruler body 1 is rotatably connected with a fixing ring 11, and the second ruler body 2, the third ruler body 3 and the fourth ruler body 4 are located inside the fixing ring 11. Through the arrangement of the fixing ring 11, the ruler bodies can be effectively prevented from being unfolded after being stored. The fixing ring 11 is made of rubber material, and the rubber can increase the friction between the fixing ring 11 and the ruler bodies, so as to prevent the ruler bodies from being accidentally unfolded or falling off after being stored.

[0035] The folding telescopic water depth ruler in the embodiment realizes the folding function of the ruler bodies through the first ruler body 1, the second ruler body 2, the third ruler body 3 and the fourth ruler body 4 connected in a hinged manner, greatly reduces the storage space, makes the whole measuring ruler more convenient to carry, does not occupy too much space, is suitable for scenes that need to be frequently moved or measured in different water areas, improves the work efficiency, and the folding and unfolding of the ruler bodies can be adjusted according to actual measurement requirements. The user can select to unfold a corresponding number of ruler bodies according to different water depths to achieve the required measurement length. Through the interference fit design of the cooperating clamps 5 and the extrusion blocks 6, the clamping between the ruler bodies is realized, the perpendicularity of the ruler bodies after unfolding is ensured, and the measurement error caused by the inclination of the ruler bodies is avoided. The water writing cloth 7 embedded on the surface of the ruler body changes color after encountering water, which can clearly display the water level position, so that the user does not need to approach the water surface and can read the measurement result after pulling out, which improves the safety and facilitates the reading operation.

[0036] The working principle of the above embodiment is that: first, the ruler body is connected by the first ruler body 1, the second ruler body 2, the third ruler body 3 and the fourth ruler body 4 through the hinged mode, which makes the ruler body flexible folding and unfolding, in the storage state, the four ruler bodies are tightly folded to form a compact whole, which greatly reduces the occupied space and is convenient to carry, when water depth measurement is needed, the user can select to unfold the corresponding number of ruler bodies according to the water depth estimation value, for example, if the estimated water depth does not exceed the length of two ruler bodies, only the first ruler body 1 and the second ruler body 2 need to be unfolded, by turning over the ruler body, the extrusion block 6 is opposite to the matching clamp 5, and the stable connection between the ruler bodies is realized through interference fit, which ensures that the ruler body remains vertical after unfolding, avoiding measurement error, then, the ruler body is slowly inserted into the water until the bottom of the ruler body touches the bottom of the water, in this process, the water writing cloth 7 on the surface of the ruler body changes color when it meets water, clearly showing the water level position, this design enables the user to intuitively read the measurement result without approaching the water surface, which not only improves the safety of measurement, but also facilitates the reading operation, in addition, the threaded column 9 and the counterweight ball 10 on the right side of the fourth ruler body 4 design not only increases the stability of the ruler body under water, ensures the verticality of the measurement, but also increases the bottom gravity, so that the ruler body is more stable when inserted into the water, and is not easily disturbed by external factors such as water flow.
