[0028] This utility model provides a system for intercepting pollution in an upper reservoir, which will be described in detail below with reference to specific embodiments.

[0029] like Figure 1 As shown in the figure, an embodiment of the present invention provides a reservoir debris barrier system, including an inspection platform 1, a transport bridge 2, and a transport track 3; a debris barrier is provided below the inspection platform 1; one end of the transport bridge 2 is set on the inspection platform 1, and the other end is set on the dam body 4; the transport track 3 is set on the top surface of the transport bridge 2 and extends along its length, and both ends of the transport track 3 extend to the upper surface of the inspection platform 1 and the upper surface of the dam body 4, respectively.

[0030] It should be noted that the transport track 3 extends along the length direction of the transport bridge 2, which means that the length direction of the transport track 3 is consistent with the length direction of the transport bridge 2, and the two ends of the transport track 3 refer to the two ends of the transport track 3 along its own length direction.

[0031] In this embodiment, a transport bridge 2 is set between the maintenance platform 1 and the dam body 4, and the two ends of the transport track 3 on the transport bridge 2 extend to the upper surface of the maintenance platform 1 and the upper surface of the dam body 4, respectively. In this way, the transport track 3 can be used as a track to transport dirt from the maintenance platform 1 to the dam body 4. After the dirt at the trash rack is collected on the maintenance platform 1, a mobile trolley is used to move along the transport track 3 to quickly transport the collected dirt to the dam body 4, thereby quickly completing the dirt cleaning operation and improving the dirt cleaning efficiency of the trash rack.

[0032] It should be noted that the height of the transport bridge 2 in the reservoir can be below the normal water level. This allows the reservoir level to drop to a dead water level when cleaning is needed, exposing the transport track 3 for easy transport of waste. When cleaning is not required, the reservoir level is in the fluctuating range, and the transport bridge 2 remains below the water surface, reducing the risk of damage. Furthermore, a waterproof layer can be applied to the surface of the transport bridge 2 to extend its lifespan.

[0033] Optionally, such as Figure 1 As shown, the transport track 3 includes a first track 31, a bridge track 32, and a second track 33 that are sequentially spliced ​​along the length direction. The bridge track 32 is located on the top surface of the transport bridge 2, the first track 31 is located on the upper surface of the maintenance platform 1, and the second track 33 is located on the upper surface of the dam body 4.

[0034] In this optional embodiment, by positioning the bridge track 32 of the transport track 3 on the top surface of the transport bridge 2, the first track 31 of the transport track 3 on the upper surface of the maintenance platform 1, and the second track 33 of the transport track 3 on the upper surface of the dam body 4, the transport track 3 can pass through the maintenance platform 1, the transport bridge 2, and the dam body 4 in sequence, thereby ensuring that the mobile trolley can move back and forth between the maintenance platform 1 and the dam body 4, and improving the efficiency of waste transport.

[0035] In addition, in some other embodiments, two transport tracks 3 can be provided, and the two ends of the two transport tracks 3 are spliced ​​together to form a ring structure. In this way, the mobile trolley can move along the ring direction on the ring structure, thereby allowing multiple mobile trolleys to move continuously in a loop, which is beneficial to further improve the efficiency of waste transport.

[0036] Optionally, such as Figures 2 to 4 As shown, the top surface of the transport bridge 2 is provided with a crash barrier 21, which extends along the length of the transport bridge 2, and the two crash barriers 21 are respectively located on both sides of the bridge track 32.

[0037] Specifically, the crash barrier 21 can be made of concrete material poured on the top surface of the transport bridge 2 so that the crash barrier 21 and the transport bridge 2 are connected as one unit.

[0038] In this optional embodiment, the anti-collision railings 21 on both sides of the bridge track 32 can form a physical barrier for the bridge track 32, which can prevent the mobile trolley from accidentally falling off the transport bridge 2 when moving along the bridge track 32, thereby reducing safety risks.

[0039] Optionally, such as Figure 3 and Figure 4As shown, the top surface of the transport bridge 2 is provided with a leveling layer 22, which is located between the two anti-collision rails 21 and its top surface is arranged horizontally; the lower end of the bridge track 32 is fixed to the upper surface of the leveling layer 22.

[0040] In this optional embodiment, by designing a leveling layer 22 with a horizontally set top surface on the transport bridge 2, and fixing the lower end of the bridge track 32 to the upper surface of the leveling layer 22, the levelness of the entire bridge track 32 can be guaranteed, preventing the moving trolley from bumping along the bridge track 32 and causing dirt to fall out accidentally.

[0041] Optionally, such as Figure 5 As shown, the upper reservoir pollution interception system also includes a pressing structure 5, which includes a screw 51 and a pressure plate 52. The lower end of the screw 51 is embedded in the leveling layer 22, and the pressure plate 52 is connected to the upper end of the screw 51. The rail bottom 321 of the bridge track 32 is located between the pressure plate 52 and the leveling layer 22, and the pressure plate 52 presses the rail bottom 321 of the bridge track 32 onto the leveling layer 22.

[0042] Specifically, the pressure plate 52 may be provided with a through hole, the upper end of the screw 51 passes through the through hole, and a nut is screwed onto the upper end of the screw 51. By tightening the nut, the pressure plate 52 is pressed against the rail base 321 of the bridge track 32, thereby pressing the rail base 321 onto the leveling layer 22.

[0043] In this optional embodiment, the combination of screw 51 and pressure plate 52 can press the bottom 321 of the bridge track 32 onto the leveling layer 22, thereby fixing the bridge track 32 relative to the leveling layer 22, ensuring the stability of the bridge track 32 installed on the leveling layer 22, and making the sewage handling operation safer.

[0044] Optionally, such as Figure 5 As shown, the leveling layer 22 includes a base 221 and a track bed 222. The base 221 is disposed on the top surface of the transport bridge 2. The upper surface of the base 221 is provided with a groove 2211 extending along the length direction of the transport bridge 2. The track bed 222 is disposed in the groove 2211. The upper surface of the track bed 222 is coplanar with the upper surface of the base 221. The lower end of the bridge track 32 is fixed to the upper surface of the track bed 222.

[0045] Specifically, the upper surface of the track bed 222 is set horizontally so that the lower end of the bridge track 32 can be placed.

[0046] In this optional embodiment, the material of the base 221 may include crushed stone, which is disposed on the top surface of the transport bridge 2 to compensate for the unevenness of the transport bridge 2 and ensure the levelness of the leveling layer 22; the material of the track bed 222 may include concrete, which is disposed in the groove 2211 of the base 221 to directly support the bridge track 32 and ensure the stability of the bridge track 32.

[0047] Optionally, such as Figure 1 and Figure 2 As shown, the maintenance platform 1 is provided with a first bridge platform 11 extending vertically, and the first bridge platform 11 is provided with a support platform 111 on the side wall near the transport bridge 2; one end of the transport bridge 2 near the maintenance platform 1 is placed on the support platform 111.

[0048] Specifically, the first bridge abutment 11 can be set at one end of the maintenance platform 1 near the transport bridge 2.

[0049] In this optional embodiment, by setting a first bridge platform 11 with a support platform 111 on the maintenance platform 1, and placing the transport bridge 2 on the support platform 111, the load-bearing effect of the transport bridge 2 can be guaranteed, thereby improving the stability and load-bearing capacity of the transport bridge 2. At the same time, it can also avoid the end of the transport bridge 2 being placed directly on the maintenance platform 1, which would result in excessive occupation of the upper surface of the maintenance platform 1.

[0050] Optionally, such as Figure 1 and Figure 2 As shown, the upper reservoir pollution interception system also includes a second bridge abutment 41, which is embedded in the dam body 4 and its upper end is exposed on the upper surface of the dam body 4; the end of the transport bridge 2 near the dam body 4 is placed on the upper end of the second bridge abutment 41.

[0051] In this optional embodiment, by pre-embedding a second bridge abutment 41 in the dam body 4 and placing the transport bridge 2 on the upper end of the second bridge abutment 41, the second bridge abutment 41 can be connected to the dam body 4 as a whole. The second bridge abutment 41 has good stability, which can improve the stability and load-bearing capacity of the transport bridge 2 and make the sewage transport operation safer.

[0052] Optionally, such as Figure 1 and Figure 2 As shown, the lower end of the transport bridge 2 is provided with a first pier 23 and a second pier 24. The first pier 23 and the second pier 24 are spaced apart along the direction from the maintenance platform 1 to the dam body 4. The lower end of the first pier 23 is provided with a first pier 231, and the lower end of the second pier 24 is provided with a second pier 241.

[0053] Specifically, the cross-section of the first pier 231 is larger than that of the first pier 23, and the cross-section of the second pier 241 is larger than that of the second pier 24. The first pier 231 can be installed at the bottom of the reservoir, and the second pier 241 can be installed on the surface of the dam body 4.

[0054] In this optional embodiment, by providing a first pier 23 with a first bearing platform 231 and a second pier 24 with a second bearing platform 241 at the lower end of the transport bridge 2, the transport bridge 2 can be stably fixed to the bottom of the reservoir and the surface of the dam body 4 with the help of the first pier 23 and the second pier 24, thereby improving the stability and load-bearing capacity of the transport bridge 2 and making the sewage transport operation safer.

[0055] Optionally, the length direction of the transport bridge 2 is parallel to the length direction of the trash rack.

[0056] In this optional embodiment, by making the length direction of the transport bridge 2 parallel to the length direction of the trash rack, and since the transport track 3 extends along the length direction of the transport bridge 2, the length direction of the transport track 3 is parallel to the length direction of the trash rack. Therefore, the process of the moving trolley moving along the transport track 3 is exactly along the length direction of the trash rack, which makes it easier to collect dirt from the trash rack.

[0057] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
