Description

Technical Field

[0001] This utility model relates to the field of water level measurement technology, and more specifically, to a water level measurement device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to eliminate water hazards and develop and utilize water resources. In the field of water conservancy projects, water level measurement is a core link in water resource management, flood control scheduling, irrigation control and hydrological monitoring.

[0003] Before constructing water conservancy projects, it is necessary to accurately measure the water level in the area, which usually requires the use of water level measuring tools. For ease of movement, existing measuring tools are mostly mounted on vehicles, with the measuring rope lowered underwater via a winch mechanism. However, this method requires a cantilever design for the unwinding mechanism, which causes the vehicle's center of gravity to become unbalanced. This can easily lead to vehicle swaying during rope deployment and retrieval, affecting not only the stability of the equipment but also potentially jeopardizing measurement accuracy and operational safety. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a water level measuring device for water conservancy projects, thereby solving the aforementioned background technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] A water level measuring device for water conservancy projects includes a vehicle body, a support frame, a winding assembly, a balancing stabilizer, and a controller. The support frame is fixedly installed at the center of the vehicle body. The winding assembly is installed on the support frame and extends to the right to the outside of the vehicle body. The balancing stabilizer is installed on the left side of the support frame. The controller is installed on the balancing stabilizer to control the power supply and operation of the winding assembly.

[0007] The winding assembly includes a servo motor, a transmission rod, a winding roller, a measuring rope, and a sinker. The servo motor is fixedly mounted on the support frame, and the output end of the servo motor is fixedly connected to the transmission rod. The other end of the transmission rod passes through and is rotatably connected to the outside of the support frame and is fixedly connected to the winding roller. One end of the measuring rope is wound around and fixed to the winding roller, and the other end of the measuring rope is vertically downward and fixedly connected to the sinker.

[0008] As a further description of the above technical solution: the sinking head includes a positioning block, a movable block, a pressure sensor, and a contact head. The top of the positioning block is fixedly connected to the bottom of the measuring rope. Two movable rods are inserted into the positioning block. The bottom ends of the two movable rods slide to the bottom of the positioning block and are fixedly connected to the movable block. The pressure sensor is fixedly installed to the bottom of the positioning block. The contact head is perpendicular to the pressure sensor and fixed to the top of the movable block.

[0009] As a further description of the above technical solution: two protective net covers are fixedly connected to the outer sides of both the positioning block and the movable block, and the two protective net covers are slidably inserted into each other.

[0010] As a further description of the above technical solution: a positioning rod is fixedly installed on the right side of the vehicle body, and a guide sleeve is fixedly installed on the other end of the positioning rod. The guide sleeve has a through hole for the measuring rope to pass through.

[0011] As a further description of the above technical solution: two opposing guide wheels are rotatably mounted inside the through hole, and the measuring rope passes between the two guide wheels.

[0012] As a further description of the above technical solution: a handrail is fixedly installed on the left side of the vehicle body.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] This solution improves the overall operational stability of the equipment by setting up a balancing and stabilizing block. It utilizes a symmetrical structural design to balance the forces generated by the winding assembly, while a protective mesh cover ensures that the sensors are triggered normally and reduces underwater interference, thus improving the operational stability of the equipment. As a result, the device has the advantages of better operational stability, improved operational safety, and a more balanced and stable structure. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0022] Please see Figure 1-4 In this utility model, the water level measuring device for water conservancy projects includes a vehicle body 1, a support frame 2, a winding assembly 3, a balancing stabilizing block 4, and a controller 5. The support frame 2 is fixedly installed at the center of the vehicle body 1. The winding assembly 3 is installed on the support frame 2 and extends to the right to the outside of the vehicle body 1. The balancing stabilizing block 4 is installed on the left side of the support frame 2. The controller 5 is installed on the balancing stabilizing block 4 to control the winding assembly 3 to be powered on and operated.

[0023] The winding assembly 3 includes a servo motor 31, a transmission rod 32, a winding roller 33, a measuring rope 34, and a sinker 35. The servo motor 31 is fixedly mounted on the support frame 2. The output end of the servo motor 31 is fixedly connected to the transmission rod 32. The other end of the transmission rod 32 passes through and is rotatably connected to the outside of the support frame 2 and is fixedly connected to the winding roller 33. One end of the measuring rope 34 is wound and fixedly fixed to the winding roller 33, and the other end of the measuring rope 34 is vertically downward and fixedly connected to the sinker 35. A handrail 9 is fixedly mounted on the left side of the vehicle body 1. The handrail 9 facilitates the movement of the vehicle body 1 and makes it easy to operate.

[0024] In this invention, the device is moved to the measurement position at the edge of the water body by the vehicle body 1, with the front of the vehicle facing the water. The winding roller 33 of the winding assembly 3 is suspended above the water. Then, the controller 5 starts the servo motor 31, which drives the transmission rod 32 and the winding roller 33 to rotate, unwinding the measuring rope 34. The submersible head 35 descends into the water under gravity, gradually sinking until it touches the bottom. Upon receiving the bottom-touching signal, the controller 5 stops the servo motor 31. The water depth is then determined based on the submersion length of the measuring rope 34. Measurements show that during equipment operation, the balancing stabilizer 4 balances the weight of the take-up roller 33, keeping the vehicle body 1 stable. This results in the device having advantages such as better operational stability, improved operational safety, and a more balanced and stable structure. It solves the problem in existing technologies where measuring tools are typically mounted on a vehicle for easy movement, and the measuring rope is placed underwater for measurement using a take-up method. However, this method requires the unwinding structure to be suspended, which leads to an unstable center of gravity on the vehicle and causes the vehicle to sway during take-up and unwinding, affecting the stability of the equipment.

[0025] Please see Figure 2The recessed head 35 includes a positioning block 351, a movable block 352, a pressure sensor 353, and a contact head 354. The top of the positioning block 351 is fixedly connected to the bottom of the measuring rope 34. Two movable rods 355 are inserted into the positioning block 351. The bottom ends of the two movable rods 355 slide to the bottom of the positioning block 351 and are fixedly connected to the movable block 352. The pressure sensor 353 is fixedly installed to the bottom of the positioning block 351. The contact head 354 is perpendicular to the pressure sensor 353 and fixed to the top of the movable block 352.

[0026] In this invention, the positioning block 351 and the movable block 352 descend inside the water body. The movable block 352 touches the bottom first, and then the positioning block 351 slides down along the movable rod 355 so that the pressure sensor 353 contacts the bottom contact, thereby sending a bottom-touching signal to the controller 5 to achieve precise control of the servo motor 31 to stop.

[0027] Please see Figure 2 and Figure 4 In this case, two protective net covers 356 are fixedly connected to the outer sides of both the positioning block 351 and the movable block 352, and the two protective net covers 356 are slidably inserted into each other.

[0028] In this invention, two protective net covers 356 reduce interference from debris between the positioning block 351 and the movable block 352, and when they meet at the bottom and merge, the water can be discharged smoothly, thus improving the stability of the equipment.

[0029] Please see Figure 1 and Figure 2 The positioning rod 6 is fixedly installed on the right side of the vehicle body 1, and the guide sleeve 7 is fixedly installed on the other end of the positioning rod 6. The guide sleeve 7 has a through hole 8 for the measuring rope 34 to pass through.

[0030] In this invention, the measuring rope 34 is guided by the guide sleeve 7 on the positioning rod 6 and the through hole 8, making it more stable and reducing swaying during winding and unwinding.

[0031] Please see Figure 2 and Figure 3 The through hole 8 has two opposing guide wheels 81 mounted inside it, and the measuring rope 34 passes between the two guide wheels 81.

[0032] In this invention, the guide wheel 81 improves the resistance of the measuring rope 34 as it passes through the through hole 8, making the winding and unwinding process smoother.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
