[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1

[0033] Reference Figures 1 to 3 , which is the first embodiment of the utility model, provides a fixing mechanism that can achieve the effect of tight splicing between two cover plates, including a counterweight assembly 102 arranged in the plate body 101, a lifting assembly 103 arranged on the counterweight assembly 102; and a locking hole 201 arranged on one side of the plate body 101.

[0034] Specifically, the plate body 101 is the cover body, which adopts a non-grid solid surface structure. The solid parts are made of high-strength composite materials, have a certain pressure-bearing capacity, and have good corrosion resistance and aging resistance. It can adapt to various harsh outdoor environments, thereby extending the service life. The locking holes 201 and the locking rods 202b are adapted to each other, and their cross-diagonal settings are arranged on both sides of the plate body 101. During the installation process, the locking holes 201 and the locking rods 202b on the opposite sides of the two plate bodies 101 are plugged and connected to achieve a tight splicing between the two plate bodies 101. It can be quickly installed and disassembled, while maintaining the stability of the overall structure, preventing the cover from loosening or offsetting when people walk or carry objects.

[0035] Further, a counterweight plate 102b is provided on the inner wall of the plate body 101. The counterweight plate 102b is in a "T" shape and is movably connected in a counterweight groove 102a formed on the lower side of the plate body 101. The counterweight plate 102b can balance and stabilize the plate body 101, improving the stability of the plate body 101. Two sets of lifting components 103 are provided, respectively arranged near the front and rear sides of the upper part of the plate body 101, including a groove 103a formed on the cover plate and a pull rod 103b in the groove 103a. The pull rod 103b is in a "匚" shape, and a limiting rod 103c is provided at the lower end of the pull rod 103b. Sliding grooves 103d are formed on the upper surface of the counterweight plate 102b near the front and rear sides. The length of the sliding groove 103d is equal to the length of the limiting rod 103c but greater than the length of the pull rod 103b. This enables the limiting rod 103c to slide up and down in the sliding groove 103d, and ensures that the pull rod 103b does not脱离 the sliding groove 103d through the limitation of the limiting rod 103c, thereby restricting the movement range of the pull rod 103b. The presence of the limiting rod 103c can also play a guiding role. By the two ends of the limiting rod 103c fitting the inner walls on both sides of the sliding groove 103d, the fixed position of the limiting rod 103c can guide the pull rod 103b to perform a specified linear motion in the sliding groove 103d. The movement of the limiting rod 103c in the sliding groove 103d not only restricts the position of the pull rod 103b but also ensures that the pull rod 103b maintains a stable movement trajectory during the sliding process, effectively controlling the movement mode and range of the pull rod 103b.

[0036] It should be noted that the part "拉杆103b不会脱离滑动槽103d" in the original text seems to be an incorrect expression. I translated it as "the pull rod 103b does not脱离 the sliding groove 103d" for the sake of literal translation. It might be more appropriate to say "the pull rod 103b does not脱离 the sliding groove 103d" or "the pull rod 103b does not脱离 the sliding groove 103d" depending on the correct meaning. You can adjust it according to the actual situation.In use, when the plate body 101 is placed stably, due to the gravity of the counterweight plate 102b itself, the counterweight plate 102b moves vertically downward, and its lower surface fits against the inner wall of the counterweight groove 102a. At this time, the lower end of the pull rod 103b can move downward through the limiting rod 103c in the sliding groove 103d, and the outer side of the limiting rod 103c will contact the bottom of the inner wall of the sliding groove 103d. At this time, the upper end of the pull rod 103b will be limited in the groove 103a, but there is still a gap between the outer wall of the middle part of the pull rod 103b and the bottom of the inner wall of the groove 103a, which is convenient for the staff to hold the pull rod 103b, so that the pull rod 103b will not protrude above the plate body 101, and the upper part of the plate body 101 can be kept flat to avoid tripping people. After several plate bodies 101 are tightly connected together through the locking holes 201 and the locking rods 202b, when it is necessary to maintain the inside of the optical cable trench or replace the plate body 101 and the plate body 101 needs to be抽出, we can put our fingers into the groove 103a, hold the pull rod 103b and lift it upward. Until the outer side of the limiting rod 103c contacts the upper side of the inner wall of the sliding groove 103d, we need to increase the applied force to overcome the gravity brought by the counterweight plate 102b, so as to drive the counterweight plate 102b to move upward. When the counterweight plate 102b moves upward, it can unlock the locking holes 201 and the locking rods 202b through the components in the fixing unit 200. As the counterweight plate 102b moves upward, its upper side will fit against the upper side of the inner wall of the counterweight groove 102a, and the plate body 101 can be driven to move upward to achieve the effect of moving the plate body 101.

[0037] Embodiment 2

[0038] Referring to Figures 4 to 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides the fixing unit 200 of the fixing mechanism to solve the problem that one of the plate bodies 101 cannot be taken out at any time after several plate bodies 101 are tightly connected through the locking holes 201 and the locking rods 202b. Telescopic grooves 202a are opened at positions close to the diagonal corners on both sides of the plate body 101. A locking rod 202b is arranged in the telescopic groove 202a. The other end of the locking rod 202b is fixedly installed with a connecting seat 202c. The connecting seat 202c is in a "C" shape, and a displacement plate 203b is fixedly connected to its inner side. Displacement grooves 203a in the shape of a "convex" are opened at positions close to the diagonal corners on both sides of the inner wall of the counterweight groove 102a. The bottom of the displacement plate 203b is adapted to the displacement groove 203a and is slidably connected in the displacement groove 203a. The function of the displacement groove 203a in the counterweight groove 102a is mainly to guide and stabilize the displacement plate 203b, ensure the stability of its movement track in the counterweight groove 102a, and at the same time provide additional support to make the movement process of the displacement plate 203b smoother and more controllable.

[0039] Furthermore, the lower side of the displacement plate 203b is provided with an inclined surface 204d in the shape of an inclined plane, and the upper side thereof is provided with an inclined surface 205c in the shape of an inclined plane. A connecting plate 204a is provided on both sides of the counterweight plate 102b and matched with the displacement plate 203b. The lower side of the connecting plate 204a is provided with a downward pressure surface 205b, which is parallel to the inclined surface 205c and always fits the inclined surface 205c. A triangular block 204b is fixedly connected to a position near one side of the lower part of the connecting plate 204a. A pushing surface 204c is provided on the upper side of the triangular block 204b. The pushing surface 204c is parallel to the inclined surface 1 204d and always fits the inclined surface 1 204d. A through groove 205a is opened at the central position of the upper surface of the connecting plate 204a, and the upper protruding part of the displacement plate 203b is movably connected in the through groove 205a.

[0040] When in use, in the first embodiment, when the plate body 101 is lifted up, the counterweight plate 102b will make a linear upward motion. During this process, the counterweight plate 102b will drive the triangular block 204b to move upward through the connecting plate 204a, and the inclined surface on the upper side will apply a force in the other direction to the inclined surface 204d of the displacement plate 203b on the other side of the triangular block 204b, thereby driving the displacement plate 203b to move in the other direction, thereby driving the locking rod 202b to move toward the bottom of the telescopic groove 202a through the connecting seat 202c, so that the locking rod 202b is separated from the locking hole 201 of the other plate body 101, and the locking rod 202b and the locking hole 201 are unlocked. When the plate 202b and the locking hole 201 are tightly spliced, the plate can be placed stably and moved downward under the gravity of the counterweight plate 102b. During the movement, the counterweight plate 102b drives the connecting plate 204a to move downward, and the lower pressure surface 205b on the lower side thereof applies a force in the direction of one side to the upper inclined surface 205c of the displacement plate 203b. Since the position of the displacement plate 203b is limited by the displacement groove 203a, the displacement plate 203b can only move in the direction of one side, thereby driving the locking rod 202b to move in the direction of one side through the connecting seat 202c, so that a part of the locking rod 202b protrudes from the notch of the telescopic groove 202a, and the protruding part contacts the locking hole 201 of the other plate body 101, completing the splicing work.

[0041] Example 3

[0042] Reference Figure 6 to Figure 7, which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides an outdoor cable trench protective cover plate, which solves the problem of the existing cover plate drainage system crossing, and includes the fixing mechanism in the above embodiment, including a plate body 101 with a slope 301a inclined to the other side on the upper surface, and a wavy pattern 301b is arranged on the upper surface of the plate body 101. The wavy metal pattern reduces the risk of people or other objects slipping, and the wavy pattern 301b can also divert rainwater on the slope 301a to one side.

[0043] Specifically, a drainage groove 302a is provided near the other side of the upper surface of the plate body 101, and one end of the drainage groove 302a is connected to the drainage system of the photovoltaic ditch. A rotating plate 302b is rotatably connected to the inner wall of the drainage groove 302a near one end through a rotating shaft. When the rotating plate 302b is in a vertical state, there is a large gap between its lower part and the bottom of the inner wall of the drainage groove 302a. A float 302c is provided between the gaps. The upper end of the float 302c is fixedly connected to the lower end of the rotating plate 302b. The rotating plate 302b is provided with a plurality of buoys. The port at one end of the drainage trough 302a is arranged. When it is not raining, the rotating plate 302b cooperates with the float 302c to block the port at one end of the drainage trough 302a to prevent leaves or other impurities from entering the drainage system and causing blockage. When rainwater is diverted into the drainage trough 302a through the slope 301a, since the density of the float 302c is greater than that of water, when rainwater flows in the drainage trough 302a, the float 302c will float on the water surface, thereby pushing the rotating plate 302b to rotate, so that the rainwater can flow into the drainage system.
