[0002] In highway engineering, especially during expressway construction, after the entire roadbed and bridges are completed, the original construction access roads are excavated and restored. Subsequent construction water is often transported by water trucks via interchanges to water intake points, involving long distances. When the affected sections include bridges spanning rivers, the traditional method of using pumps to draw water from the bridge is problematic. Due to the lack of effective securing of the water pipes, personnel must lift the pipes from the bridge deck to the water truck's inlet. Furthermore, the central median strip separates the left and right lanes, making it difficult and inconvenient to use a single device to draw water from both sides simultaneously. Therefore, it is essential to develop a safe, efficient, and economical water intake device for bridges spanning rivers where water intake is required. Utility Model Content

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0027] Please refer to the following: Figures 1 to 6 The cross-river bridge deck water intake device of this embodiment includes a support mechanism 1 for spanning the left and right spans of the bridge deck, a water intake mechanism 2 installed on the support mechanism 1, and a span passage assembly 3 installed on the support mechanism 1. The water intake mechanism 2 includes a water pump 21, a main pipe 22, a branch pipe 23, a T-joint 24, and an electrical control box 25. The electrical control box 25 is electrically connected to the water pump 21. The outlet of the water pump 21 is connected to the first end of the main pipe 22. The second end of the main pipe 22 is connected to two branch pipes 23 through the T-joint 24 to achieve simultaneous water supply to the left and right spans of the bridge deck.

[0028] In this embodiment, the cross-river bridge deck water intake device has a support mechanism 1 spanning the left and right spans of the bridge deck. The water pump 21 is placed below the water surface of the water source. The water pump 21 is connected to the outlet of the water pump 21 and the inlet of the tee connector 24 through the main pipe 22. The two outlets of the tee connector 24 are respectively connected to two branch pipes 23. The electrical control box 25 is installed on the support mechanism 1, which allows the power supply of the water pump 21 to be switched on and off on the bridge deck, thereby achieving simultaneous water supply to the left and right spans of the bridge deck. If the cross-river bridge deck water intake device or water truck malfunctions and needs to be repaired, it can be directly crossed through the span passage component 3 to the side where the electrical control box 25 is installed to disconnect the main power supply, avoiding long detours from one side. In other special cases where crossing is required, it can be done through this passage. The safety conditions meet the requirements, and a lot of detour time is saved. Its structure is simple, the operation is convenient, and it can achieve simultaneous water intake from the left and right spans of the bridge deck.

[0029] In this embodiment, the water pump 21 is connected to the support mechanism 1 via a hoisting rope. The water pump 21 is also connected to the support mechanism 1 along the main pipeline 22 via the hoisting rope, which helps to fix the depth of the water pump 21 in the water source and prevents the main pipeline 22 from breaking due to the weight of the water pump 21. Optionally, the support mechanism 1 is equipped with a winding roller for winding and unwinding the hoisting rope, and the hoisting height of the water pump 21 is adjusted by rotating the winding roller. Optionally, one end of the winding roller is equipped with a handle, allowing the operator to drive the winding roller to rotate via the handle. This design is simple and has low production costs. Optionally, the winding roller is driven by a motor, which is electrically connected to the electrical control box 25. The operator controls the motor through the electrical control box 25 to adjust the hoisting height of the water pump 21, resulting in a high degree of automation and reducing the labor intensity of the operators.

[0030] like Figure 3 and Figure 4 As shown, in this embodiment, a pressure sensor 27 is installed at the connection between the tee joint 24 and the main pipe 22. The pressure sensor 27 is electrically connected to the electrical control box 25. The pressure sensor 27 is located on the main pipe 22 near the tee joint 24 and is used to monitor the water pressure in the pipe in real time and transmit the detected water pressure information to the feedback control system. The feedback control system is installed in the electrical control box 25 and connected to the power double-off switch. The power cord of the water pump 21 is led out from the feedback control system. The feedback control system can preset the pressure value. The pressure sensor 27 on the main pipe 22 is connected to the feedback control system via a wire. The system connects to the main pipeline 22 and collects water pressure data in real time. Based on the data fed back by the pressure sensor 27, it reacts to determine whether the water pump 21 is powered on. When the water pressure value fed back by the pressure sensor 27 is lower than the preset value, the feedback control system powers on the water pump 21, and the water pump 21 starts working to supply water to the main pipeline 22. When the water pressure value fed back by the pressure sensor 27 is equal to or higher than the preset value, the feedback control system cuts off the power to the water pump 21, and the water pump 21 stops supplying water. It is understood that the pressure sensor 27 can also be set on the tee connector 24, as long as it can monitor the water pressure value of the main pipeline 22.

[0031] like Figure 3 and Figure 4 As shown, in this embodiment, the support mechanism 1 includes a base frame 11, tripods 12 spaced along the width of the bridge deck 100 on the base frame 11, and a cantilever main beam 13 on the top of the tripods 12. A tee joint 24 is arranged on the base frame 11, and the branch pipe 23 is suspended on the bridge deck along the cantilever main beam 13 at one end away from the cantilever main beam 13. The size of the base frame 11 is determined according to the site conditions. When water is taken from a site where the crash barriers 101 have been completed, the span of the base frame 11 is the distance between two adjacent crash barriers 101 on the left and right sides of the bridge deck, ensuring that the base frame 11 can be stably placed on the two crash barriers 101. When water is taken from a site where the crash barriers 101 have not been completed, the base frame 11 is placed directly on the left and right sides of the bridge deck, and the span of the base frame 11 is determined according to the width of the gap between the left and right sides. Two tripods 12 are symmetrically arranged on the base frame 11. The cantilever main beam 13 is welded to the top of the two tripods 12, fixing the two tripods 12 together. The bottom of the tripods 12 is welded to the base frame 11. Optionally, the base frame 11 is fixedly connected to the two guardrails 101 by bolts to ensure that the cantilever main beam 13 remains stable under the pressure of the branch pipe 23 and the water flow. The water inlet of the water truck is generally located at the top of the water tank (if located in the middle or bottom of the water tank, a pressurization device is needed to fill the water tank). Therefore, by raising the outlet height of the branch pipe 23 through the tripods 12 and the cantilever main beam 13, water can be smoothly injected into the water tank of the water truck and filled. It can be understood that the number of tripods 12 can also be three, four or more, adjusted according to the span of the base frame 11 to ensure the structural strength of the base frame 11.

[0032] like Figure 3 and Figure 4 As shown, in this embodiment, a water pipe switch 26 is installed on the branch pipe 23. A flexible hose 28 for connecting the water inlet of the water receiving truck is connected to the end of the branch pipe 23 away from the tee joint 24. The flexible hose 28 facilitates the adjustment of the water outlet height and is suitable for different models of water receiving trucks. It is convenient to connect the water outlet to the water receiving truck. At the same time, the flexible hose 28 can reduce the impact force at the water outlet and prevent water from splashing when receiving water. By controlling the water pipe switches 26 on the two branch pipes 23 respectively, the water supply control on the left and right sides of the bridge deck can be realized. It can be understood that the water pipe switch 26 can also be installed on the tee joint 24 or the flexible hose 28.

[0033] like Figure 5As shown in this embodiment, the bottom frame 11 is provided with gate-shaped brackets 15 for engaging the crash barrier 101. The bottom frame 11 is provided with two rows of gate-shaped brackets 15 along the width direction of the bridge deck 100. Each row of gate-shaped brackets 15 has at least two. Compared with fixing the bottom frame 11 to the crash barrier 101 with bolts, using the gate-shaped brackets 15 on the bottom surface of the bottom frame 11 to engage the top surface of the crash barrier 101 can not only prevent the bottom frame 11 from slipping off the crash barrier 101, but also simplify the assembly operation and reduce the labor intensity of assembly.

[0034] like Figure 6 As shown, in this embodiment, the bottom frame 11 and the portal frame 15 are slidably connected by a sliding groove and pin structure. The pin 151 is provided with a locking nut 152 for limiting the relative position of the bottom frame 11 and the portal frame 15. The bottom frame 11 is provided with a sliding groove 111 and a clearance groove 112. The portal frame 15 is embedded with a sliding pin 151. The sliding pin 151 passes through the sliding groove 111 and is screwed to the locking nut 152. The clearance groove 112 provides operating space for rotating the locking nut 152. In use, the relative position of the portal frame 15 and the bottom frame 11 is adjusted according to the distance between two adjacent guardrails 101 on the left and right sides of the bridge deck. When the portal frame 15 slides to the designated position, the locking nut 152 is tightened to fix the relative position of the bottom frame 11 and the portal frame 15. This method has a wide range of applications.

[0035] like Figure 3 As shown, in this embodiment, the support mechanism 1 further includes reinforcing ribs 14 to enhance structural strength, thereby stabilizing the cantilever main beam 13, reducing vibration of the cantilever main beam 13, and preventing water splashing when water is collected. Optionally, reinforcing ribs 14 are arranged between the tripod 12 and the base frame 11 to enhance the connection strength between the tripod 12 and the base frame 11 and prevent the tripod 12 from tipping over. Optionally, reinforcing ribs 14 are arranged between the tripod 12 and the cantilever main beam 13 to enhance the connection strength between the tripod 12 and the cantilever main beam 13 and prevent the cantilever main beam 13 from bending and deforming. Optionally, reinforcing ribs 14 are arranged between the support rods of the tripod 12 to enhance the structural strength of the tripod 12 and prevent the tripod 12 from deforming.

[0036] like Figure 4As shown, in this embodiment, the span passage component 3 includes a span base plate 31 installed on the base frame 11 and a ladder 32 for accessing the span base plate 31. The ladder 32 is hinged to the base frame 11 via a hinge seat 33. The span base plate 31 is made of rectangular steel pipes welded at intervals, with both ends of the rectangular steel pipes welded to the base frame 11. On the one hand, this improves the structural strength of the base frame 11; on the other hand, if the water intake device on the bridge deck malfunctions and needs maintenance, the main power supply needs to be disconnected at the side where the electrical control box 25 is installed. The span base plate 31 can provide a passage for workers to cross the left and right spans of the bridge deck, avoiding long detours from one side. In other special cases where crossing is required, passage can be directly made through the span base plate 31. The safety conditions are met, and a significant amount of detour time can be saved. The ladders 32 are located on the left and right sides of the bridge deck. When water is drawn from the site where the crash barrier 101 has been completed, the bottom frame 11 spans across the crash barrier 101 on the left and right sides of the bridge deck. There is a height difference between the bottom plate 31 of the span and the bridge deck 100, and workers can climb up and down to the bottom plate 31 of the span through the ladders 32, which can reduce the difficulty of passage. When water is drawn from the site where the crash barrier 101 has not been completed, the bottom frame 11 spans across the left and right sides of the bridge deck, and the ladders 32 can be retracted and folded, which does not affect the passage of workers from the bottom plate 31 of the span, nor does it affect the water truck to draw water and other construction operations. Its structure is simple and can be applied to different construction sites. Optionally, the width of the bottom frame 11 along the extension direction of the bridge deck is 1.2m to 1.5m. When the width of the bottom frame 11 is greater than 1.5m, the overall weight and size of the water intake device will be too large, making it inconvenient to install. Due to the structure of the tripod 12 being wider at the bottom and narrower at the top, when the width of the bottom frame 11 is less than 1.2m, it will cause inconvenience for workers to pass through.

[0037] like Figure 4 As shown, in this embodiment, the support mechanism 1 also includes a guardrail 16. The horizontal bars of the guardrail 16 are welded to the two side tripods 12. This not only improves the connection strength at the middle section of the two tripods 12 and reduces vibration of the tripods 12, but also ensures the safety of workers passing through. Optionally, the horizontal bars of the guardrail 16 are connected to the bottom frame 11 by diagonal bars, which improves the stability of the horizontal bars of the guardrail 16 and prevents bending and deformation of the horizontal bars of the guardrail 16.

[0038] After the installation of the cross-river bridge deck water intake device of this utility model is completed, a preset water pressure standard value is set on the electrical control box 25. At this time, since there is no water pressure in the main pipeline 22, the water pressure value monitored by the pressure sensor 27 does not reach the preset water pressure standard value. The electrical control box 25 powers on the water pump 21, and the water pump 21 starts to work, supplying water to the main pipeline 22. The pressure sensor 27 simultaneously monitors the pipeline pressure as it gradually increases. When the water pressure value of the main pipeline 22 monitored by the pressure sensor 27 reaches the preset water pressure standard value, the electrical control box 25 automatically cuts off the power to the water pump 21, and the water pump 21 stops working. When there is a water intake requirement, the water receiving truck travels to the underside of the cantilever main beam 13, ensuring that the hose 28 can effectively extend into the water receiving port of the water receiving truck. At this time, the water pipe switch 26 on the branch pipeline 23 on the water receiving side is opened to start supplying water to the water receiving truck. At the same time, the pressure sensor 27 detects that the water pressure in the main pipeline 22 is less than the preset value. When the water pressure reaches the standard value, the electrical control box 25 starts to power the water pump 21, and the water pump 21 starts to work continuously. After the water is collected, the water pipe switch 26 on the water collection side is turned off, and the water supply pipeline is in a closed state. Under the water supply pressure of the water pump 21, the water pressure of the main pipeline 22 gradually reaches the preset water pressure standard value. At this time, the electrical control box 25 disconnects the power supply to the water pump 21 until the next use, and so on. When there is a need for crossing, the ladder 32 can be lowered and the span base plate 31 can be used to cross the span. If the water collection device malfunctions and needs to be repaired, it can be directly crossed through the span base plate 31 and the main power supply can be disconnected on the side where the electrical control box 25 is installed, avoiding long detours from one side. Other special cases that require crossing can all be done through this passage. The safety conditions meet the requirements and save a lot of detour time. Its structure is simple and easy to operate. It can realize water collection from both sides of the bridge deck at the same time, or water collection from one side of the bridge deck.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
