Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural water conservancy equipment and relates to a water conservancy detection and sampling device for water conservancy projects. Background Art

[0002] The healthy development of agriculture is one of the most concerned objects in today's society. In the development of agriculture, the quality of water conservancy projects determines whether agriculture can develop healthily. Therefore, in the process of agricultural production, at present, when diverting water into farmland ditches, generally, staff members open the baffle at the entrance of the ditch and wait for the water to flow into the ditch, and then put down the baffle to close it, completing the work of storing water in the ditch.

[0003] In view of the current technology, the existing farmland water conservancy projects have the following deficiencies: 1. With the development of agricultural technology, the requirements for the quality of farmland water are gradually increasing, and it is necessary to monitor the quality of irrigation water in farmland. At present, the water quality monitoring adopts regular sampling, which is rather troublesome and time-consuming; 2. During the irrigation process, it is easy for the water quality to deteriorate due to the artificial input of pollutants such as pesticides or batteries, which is likely to cause pollution to the farmland irrigation water, resulting in crop yield reduction or even soil quality degradation, imposing a certain burden on increasing farmland production and income; 3. Currently, the closing of farmland gates often adopts the up-and-down opening and closing method, which is prone to poor opening and closing due to blockage, and this is also a problem that needs to be solved. Therefore, in view of the above deficiencies, a water conservancy detection and sampling device for water conservancy projects is proposed to solve the problems of real-time water quality monitoring and avoiding blockage during the irrigation process.

[0017] Example 1, as Figures 1-3 shown, this embodiment provides a water conservancy detection sampling device for water conservancy projects, including: a water conservancy project pipeline 1, a sluice is installed on one side of the water conservancy project pipeline 1. The sluice includes a gate 3 and a doorframe 2. The gate 3 is installed on the track in the middle of the doorframe 2. A transversely installed sampling hole is provided on the upper surface of the doorframe 2. A storage vessel can be provided at the sampling hole.

The cylinder body of the hydraulic cylinder is hinged to the foundation on the doorframe 2. Between the rod end of the piston rod of the hydraulic cylinder and the first and second connecting rods, there is a connecting rod mechanism. The hydraulic cylinder drives the connecting rod mechanism to drive the included angle between the first and second connecting rods to gradually increase to the position where the two rod bodies are straight. Due to the working needs, the first and second connecting rods will be in the position states of pushing the gate 3 plate to stand upright and rotating it to the position of dumping water. For the convenience of description, the upper and lower ends of the first and second connecting rods refer to the parts in their obliquely supported states. The cylinder body of the hydraulic cylinder is hinged to the foundation on the doorframe 2. Therefore, there will be no factor of sediment deposition affecting the rotation of the hydraulic cylinder. At the same time, the hydraulic cylinder does not need to be directly hinged to the gate 3 plate, but supports the gate 3 plate by driving the included angle between the first and second connecting rods to gradually increase to the position where the two rod bodies are straight. When the gate 3 is stably in the water-blocking state, only the first and second connecting rods support the gate 3 plate, and there is no need to additionally set up a support rod and a locking and unlocking device beside the hydraulic cylinder.
