Description

Technical Field

[0001] This invention relates to the field of water level observation technology, specifically to a water level observation device for hydrogeological exploration. Background Technology

[0002] Hydrogeological investigation, also known as hydrogeological survey, refers to the hydrogeological investigation and research conducted to ascertain the hydrogeological conditions of a region. Its aim is to understand the formation, distribution, and movement patterns of groundwater and surface water. This provides a basis for the rational exploitation and utilization of water resources and the correct design and construction of foundation and piling projects. It includes both underground and above-ground hydrogeological investigation. Groundwater hydrogeological investigation mainly investigates and studies the changes in groundwater level, flow direction, and chemical composition at different times of the year, ascertains the burial conditions and corrosiveness of groundwater, determines the potential changes and impacts of groundwater during the construction and use of buildings, and proposes prevention and control recommendations.

[0003] Chinese patent CN116558895A discloses a hydrogeological exploration water level observation device, belonging to the technical field of geological exploration equipment. It includes a hoisting mechanism, a sampling mechanism, and a storage mechanism. The hoisting mechanism is equipped with a hoisting base, the sampling mechanism is equipped with a side box and a collection component, and the storage mechanism is equipped with a storage box and a display component. The hoisting mechanism is rotatably mounted on the side box. There are four sets of storage boxes, each set of which is fixedly mounted on the side of the side box. Each set of storage boxes has multiple boxes. The storage boxes are connected to the side box through the display component. The lower part of the side box is provided with a flower-shaped opening. The collection component is installed in the flower-shaped opening of the side box and is connected to the display component through the flower-shaped opening of the side box.

[0004] In existing technologies, water level monitoring is mostly achieved using water level monitoring stations. These stations typically have a support rod fixed to the bank, with a crossbar attached to the rod. The end of the crossbar extends above the water surface and is fitted with a level radar for real-time water level monitoring. However, this structure presents challenges for maintaining and replacing the level radar. Because the crossbar is fixed to the support rod and extends above the water surface, it's difficult to remove the level sensor. Removal requires disassembling the entire support rod before the sensor can be removed. Furthermore, the radar level sensor is fixed with a flange using bolts, making disassembly and installation extremely cumbersome. The overall setup significantly increases the difficulty of maintaining the radar level sensor and raises the labor intensity of maintenance.

[0005] Therefore, it is necessary to provide a water level monitoring device for hydrogeological exploration to solve the above-mentioned technical problems. Summary of the Invention

[0019] (III) Beneficial Effects

[0020] This invention provides a water level monitoring device for hydrogeological exploration. Compared with the prior art, it has the following advantages:

[0021] 1. This application involves mounting a crossbar rotatably on a support rod and setting up a rotation mechanism. When the radar level sensor needs to be disassembled, the rotation mechanism drives the crossbar to rotate, causing it to move from the water surface to the shore. Workers can directly install and disassemble the radar level sensor without having to completely disassemble the support rod from the ground. Simultaneously, a synchronous locking mechanism automatically releases the radar level sensor from its locking position until it reaches the shore, at which point it can be directly removed. Compared to existing technologies, this significantly reduces the steps involved in disassembling and assembling the radar level sensor on the water level monitoring equipment, lowers the difficulty of disassembly and assembly, and makes it easier for people to maintain, repair, and replace the radar level sensor on the water level monitoring device.

[0022] 2. The synchronous locking mechanism is mechanically linked to the rotation of the crossbar, and the locking work is completed by using the power of the crossbar's rotation. There is no need to add a separate power source, which reduces the operation and maintenance costs and ensures the timeliness of the locking work. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8This invention provides a technical solution: a hydrogeological exploration water level monitoring device, comprising a mounting plate 1, a support rod 2 fixed to the top of the mounting plate 1, and reinforcing ribs 10 symmetrically fixed to the top of the mounting plate 1. One side of the reinforcing ribs 10 is fixed to the outer wall of the support rod 2, improving the connection strength between the mounting plate 1 and the support rod 2. During use, the mounting plate 1 is fixed to the waterfront by pouring a cement base and pre-embedding expansion bolts, thus completing the installation of the entire device. The upper end of the support rod 2 is rotatably connected to a rotating sleeve 3 via a bearing, and a crossbar 4 is fixed to the outer wall of the rotating sleeve 3. A base plate 5 is fixed to the end of the crossbar 4. A U-shaped groove 51 is formed on one side of the base plate 5. A radar liquid level sensor 6 is nested and fixed in the inner wall of the U-shaped groove 51. The radar liquid level sensor 6 includes a ring 61 formed on its outer wall. The bottom of the ring 61 contacts the top surface of the base plate 5. A pre-positioning mechanism 7 for pre-positioning the radar liquid level sensor 6 is fixed on the inner wall of the U-shaped groove 51. A rotation mechanism 8 for driving the crossbar 4 to rotate is fixed at the upper end of the support rod 2. A synchronous locking mechanism 9 for automatically locking and unlocking the radar liquid level sensor 6 during the rotation of the crossbar 4 is fixed at the top of the crossbar 4.

[0034] Compared with the prior art, when the radar level sensor 6 needs to be maintained during use, the drive rotation mechanism 8 is used to rotate the crossbar 4 to the shore. During the rotation, the synchronous locking mechanism 9 automatically unlocks the sensor, allowing people to remove the radar level sensor 6 directly from the shore. This greatly reduces the difficulty of disassembling and assembling the radar level sensor 6 on the water level observation device, saves disassembly and assembly time, and facilitates the maintenance and replacement of the radar level sensor 6.

[0035] The pre-positioning mechanism 7 includes symmetrically and equidistantly formed rubber protrusions 71 on the inner wall of the U-shaped groove 51. The rubber protrusions 71 are hemispherical and press against the radar level sensor 6. When the crossbar 4 is on the shore and the radar level sensor 6 is installed, the radar level sensor 6 is inserted into the U-shaped groove 51, ensuring that the ring 61 on it is in contact with the top surface of the substrate 5. During the insertion process, the radar level sensor 6 will press against the rubber protrusions 71 to deform it until the radar level sensor 6 is fully inserted into the deepest part of the U-shaped groove 51. The rubber protrusions 71 then return to their shape and press against the outer wall of the radar level sensor 6 to complete the pre-positioning of the radar level sensor 6. When disassembling, the radar level sensor 6 can be directly pulled out.

[0036] The rotating mechanism 8 includes a fixed sleeve 81, a fixed plate 82, a worm 83, a worm wheel 84, and a motor 85. The upper end of the support rod 2 is fixed with the fixed sleeve 81, and the upper outer wall of the fixed sleeve 81 is fixed with the fixed plate 82. The worm 83 is rotatably connected to the fixed plate 82 through a bearing. The lower end of the outer wall of the rotating sleeve 3 is fixed with the worm wheel 84, which meshes with the worm 83. The top of the fixed plate 82 is also fixed with a motor 85, which is a geared motor 85. The end of the worm 83 is fixed to the end of the motor 85.

[0037] When the drive bar 4 rotates, the drive motor 85 rotates, which drives the worm gear 83 to rotate, which in turn drives the worm wheel 84 to rotate, causing the rotating sleeve 3 to rotate, thereby causing the drive bar 4 to rotate.

[0038] The synchronous locking mechanism 9 includes a bidirectional screw 91, a moving bar 92, a clamping block 93, a gear 94, a movable bar 95, a rack 96, a cam 97, and a spring 98. The top of the base plate 5 is rotatably connected to the bidirectional screw 91 via bearings. Two moving bars 92 are symmetrically threaded to both ends of the bidirectional screw 91 through threaded holes. The moving bars 92 are slidably connected to the top of the base plate 5. A clamping block 93 is fixed to the end of each moving bar 92. The two clamping blocks 93 are clamped onto the outer wall of the ring 61, with the clamping blocks 93 inclined on the side closest to the ring 61. A gear 94 is fixed to the middle of the bidirectional screw 91. The top of the crossbar 4 is slidably connected to the movable bar 95. A connecting frame 11 is symmetrically fixed to the top of the crossbar 4. The movable bar 95 is slidably connected to the two... Inside the connecting frame 11, the connecting frame 11 defines the movable bar 95 so that it can slide along the length direction of the crossbar 4. The end of the movable bar 95 is fixed with a rack 96, which meshes with a gear 94. The upper end of the outer wall of the support rod 2 is also fixed with a cam 97. The end of the movable bar 95 is in pressure contact with the outer wall of the cam 97. The outer wall of the movable bar 95 is also fixed with a spring 98, the end of which is fixed with the outer wall of the crossbar 4. The end of the movable bar 95 near the cam 97 is rotatably connected to a roller 12 through a shaft pin. The roller 12 is in pressure contact with the outer wall of the cam 97. The setting of the roller 12 allows the end of the movable bar 95 to roll on the outer periphery of the cam 97 instead of sliding, thus reducing friction.

[0039] The diagram shows the entire device in its installed state, with the radar level sensor 6 positioned above the water surface. When maintenance or replacement of the radar level sensor 6 is required, the rotating mechanism 8 causes the crossbar 4 to rotate. During the rotation of the crossbar 4, the cam 97 remains stationary. Under the tension of the spring 98, the roller 12 remains pressed against the outer wall of the cam 97. However, the roller 12 continuously moves from the outer periphery of the cam 97's larger radius to its smaller radius. During this process, the spring 98 pulls the movable strip 95 to slide relative to the crossbar 4 towards the support rod 2, thereby causing the rack 96 to slide and the gear 94 to rotate. This causes the bidirectional screw 91 to rotate, resulting in the two movable strips 92 sliding away from each other. Consequently, the two clamping strips move away from each other and separate from the ring 61. This completes the unlocking of the radar level sensor 6 as the crossbar 4 rotates to the shore. When the crossbar 4 rotates back to the water surface, the process is reversed, ultimately locking the radar level sensor 6 again.
