Description

Technical Field

[0001] This invention relates to the field of water level early warning technology, and specifically to a hydrological and water resources water level early warning device. Background Technology

[0002] Hydrological and water resources monitoring refers to monitoring information on the distribution, formation, and evolution of water resources, with water resources as the main research object. Hydrological and water resources monitoring is of great significance to water conservancy planning, water project construction and management, flood control and drought relief, and water resources management and protection. Existing water level early warning devices are relatively troublesome to install and dismantle, and cannot set warning water levels according to needs, which limits their scope of use. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a well-designed and easy-to-use hydrological and water resource water level early warning device, which solves the problem of not being able to set warning water levels according to needs, thereby making its application scope unrestricted.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it comprises a fixing plate, a support column, and a mounting frame; the upper surface of the fixing plate is provided with a support column, and the top end of the support column is fixed with a mounting frame, which is arranged in a "U" shape; it further comprises:

[0005] A rotating mechanism is disposed within a fixed plate and is connected to the bottom end of a support column;

[0006] The telescopic mechanism is located inside the mounting frame. A movable plate is connected to the other side of the telescopic mechanism. The movable plate passes through the mounting frame on the side away from the support column and is exposed on the outside of the mounting frame.

[0007] A winding reel is fixed to the lower surface of a movable plate, and a pull rope on the winding reel is suspended on the lower side of the movable plate.

[0008] The sleeve is suspended below the movable plate, and the bracket on the top wall of the sleeve is connected to the lower end of the pull rope.

[0009] The insertion tube is movably inserted inside the sleeve. The protruding edge on the lower side of the insertion tube abuts against the bottom wall of the sleeve. Several water inlet holes are provided at equal angles on the outer ring walls of the insertion tube and the sleeve.

[0010] A floating plate is provided on the lower side inside the insertion tube, and the metal sheet on the upper surface of the floating plate is configured to cooperate with the metal sheet on the top wall of the inner tube.

[0011] An alarm is fixed to one side of the top wall of the mounting frame. The alarm is connected to the float plate and the metal plate on the top wall of the sleeve through a guide. The alarm is connected to the battery, which is fixed to the top wall of the mounting frame.

[0012] An adjustment mechanism is provided inside the insertion tube and is connected to the inner top wall of the sleeve.

[0013] The counterweight is fixed on the outer bottom wall of the insertion tube, and the outer ring wall of the counterweight is set with the same arc surface as the outer ring wall of the insertion tube.

[0014] The above technical solution involves fixing the fixed plate to the edge of the water resource, then moving the movable plate via a telescopic mechanism. The movable plate, through a winding reel, moves the sleeve and insert tube, placing them within the water resource. The winding reel then lowers the sleeve and insert tube into the water resource, and under the weight of the counterweight, the bottom of the insert tube moves downwards until it reaches the inner top wall of the sleeve, reaching the highest water level. An adjustment mechanism moves the sleeve upwards to align with the normal water level. As the water level rises, the float plate moves upwards. When the metal plate on the float plate contacts the metal plate on the inner top wall of the sleeve, the circuit between the float plate, battery, and alarm is activated, triggering an alarm sound to alert monitoring personnel. When not in use, the sleeve and insert tube are moved upwards via the winding reel, and the support rod is rotated towards one side of the fixed plate. Simultaneously, the support rod moves towards the fixed plate, leaving the sleeve and insert tube suspended above one side of the fixed plate for easy storage.

[0015] As a further improvement of the present invention, a scale layer is provided on one side of the outer annular wall of the cannula, and the starting point of the scale layer is the inner bottom wall of the cannula;

[0016] The above technical solution uses a graduated layer to determine the position of the cannula as it moves downwards.

[0017] As a further improvement of the present invention, the rotating mechanism includes:

[0018] The movable block is embedded in the fixed plate, and a connecting rod is screwed to the upper side wall of the movable block via a bearing. The upper end of the connecting rod passes through a groove on the upper side wall of the fixed plate and is fixedly connected to the lower side wall of the support rod.

[0019] The gear is sleeved and fixed on the connecting rod, and the gear is slidably disposed in the strip groove on the fixed plate;

[0020] The rack is fixed to the inner wall of one side of the strip groove on the fixing plate, and the rack is meshed with the gear.

[0021] With the above technical solution, when not in use, rotating the support rod causes the connecting rod to rotate, and the rotating connecting rod causes the gear to move. As the gear moves, it moves along the rack, so that the support rod is located on one side above the fixed plate, while the sleeve and tube are suspended on the other side above the fixed plate, making them easy to store.

[0022] As a further improvement of the present invention, the front and rear sides of the lower surface of the fixing plate are screwed with plug rods by bolts, and the plug rods are all tapered.

[0023] By using the above technical solution, when fixing the fixing plate to the ground, inserting the plug into the ground increases the stability of the connection between the fixing plate and the ground.

[0024] As a further improvement of the present invention, the telescopic mechanism includes:

[0025] The mounting rod is disposed inside the mounting frame and fixed to the inner wall of one side of the mounting frame, with the front and rear ends of the mounting rod located on the front and rear sides of the mounting frame, respectively.

[0026] The guide rod is arranged in an inverted "L" shape. The vertical part of the guide rod is fixed on the upper side wall of the movable plate, and the horizontal part of the guide rod is movably inserted into the upper side wall of the mounting frame.

[0027] The telescopic link is located inside the mounting frame. The four corner ends of the telescopic link are respectively connected to sliding blocks via hinge seats. The sliding blocks are respectively slidably installed in the sliding grooves on the mounting rod and the moving plate.

[0028] The telescopic screw is installed inside the mounting rod. The rear end of the telescopic screw is screwed to the rear inner wall of the mounting rod via a bearing. The threads at both ends of the telescopic screw are arranged in opposite directions, and the threads of the telescopic screw are screwed to the sliding blocks on both sides.

[0029] A telescopic motor is fixed on the front inner wall of the mounting rod, and the output shaft of the telescopic motor is fixedly connected to the front end of the telescopic lead screw. The telescopic motor is connected to a storage battery.

[0030] With the above technical solution, the telescopic motor is started, which drives the telescopic lead screw to rotate. The telescopic lead screw drives the two sliding blocks inside the mounting rod to move through the threads at both ends. The sliding blocks drive one end of the telescopic connecting rod to move, thereby causing one side of the moving plate to move outward. The moving plate drives the winding reel to move.

[0031] As a further improvement of the present invention, the adjusting mechanism includes:

[0032] An adjusting motor is fixed on the outer top wall of the sleeve, the adjusting motor is connected to the battery, and the output shaft of the adjusting motor is inserted into the top wall of the sleeve.

[0033] The screw is screwed onto the top wall of the sleeve via a bearing, and the top end of the screw is fixedly connected to the output shaft of the regulating motor.

[0034] An internally threaded tube is sleeved on a screw rod and connected by a threaded connection. The lower end of the internally threaded tube is fixed to the inner bottom wall of the insertion tube.

[0035] The limiting blocks are multiple in number and are fixed at equal angles to the upper side of the outer annular wall of the sleeve. The limiting blocks are slidably disposed in several sliding grooves on the inner wall of the sleeve, and the inner bottom wall of the sliding groove is closed.

[0036] Using the above technical solution, the regulating motor is started, and the regulating motor drives the screw to rotate. At this time, under the limit of the limit block, the screw drives the internal threaded tube to move up and down, and the internal threaded tube drives the insertion tube to move down until the outer bottom wall of the insertion tube is at the normal water level.

[0037] As a further improvement of the present invention, the outer side cover of the regulating motor is provided with a waterproof cover, which is fixed to the outer top wall of the sleeve.

[0038] The above technical solution protects the regulating motor with a waterproof cover, preventing the water level from rising to the top of the sleeve and damaging the regulating motor.

[0039] As a further improvement of the present invention, an identification ring is provided on the outer ring wall of the insertion tube, and the upper side wall of the identification ring is set in the same plane as the inner bottom wall of the insertion tube.

[0040] The above technical solution makes it easier to determine the insertion location.

[0041] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0042] 1. The warning water level can be set according to needs, so that the scope of use is not limited and the applicability is improved;

[0043] 2. When in use, the telescopic mechanism can be used to move the warning device, making it easy to move the device above the water resource and then place it into the water resource for easy warning.

[0044] 3. When not in use, the warning device can be rotated to the top of the fixed plate to reduce the space occupied by the entire device, thus making it easier to store. Attached Figure Description

[0078] Example 4:

[0079] See Figure 1 , Figure 5-6 As shown, based on Embodiment 1, the adjustment mechanism 14 includes:

[0080] The regulating motor 14-1 is riveted and fixed to the outer top wall of the sleeve 8.

The adjusting motor 14-1 is started, which drives the screw 14-2 to rotate. At this time, under the limit of the limiting block 14-4, the screw 14-2 drives the internal threaded tube 14-3 up and down. The internal threaded tube 14-3 moves the insertion tube 9 downwards until the outer bottom wall of the insertion tube 9 is at the normal water level. During the rise of the water level, the float plate 11 moves upwards. When the metal plate on the float plate 11 contacts the metal plate on the inner top wall of the sleeve 8, the circuit between the float plate 11, the battery 13 and the alarm 12 is connected, causing the alarm 12 to sound an alarm, thus reminding the monitoring personnel. When not in use, the sleeve 8 and the insertion tube 9 are moved upwards by the winding reel 7, and then the support column 2 is rotated to one side of the fixed plate 1. When not in use, the support column 2 is rotated, and the support column 2 drives the connecting rod 4-2 to rotate. While the connecting rod 4-2 rotates, it drives the gear 4-3 to move. While the gear 4-3 moves, it moves along the rack 4-4, so that the support column 2 is located on one side above the fixed plate 1, while the sleeve 8 and the insertion tube 9 are suspended on the other side above the fixed plate 1 for easy storage.
