Description

Technical Field

[0002] In water conservancy projects, regular inspection of river silt is an important part of maintaining river health and ensuring flood control and drainage capabilities. Workers need to regularly inspect the thickness of river silt so that they can formulate corresponding cleaning and maintenance plans based on actual conditions.

[0003] After a lot of searching, it was found that announcement number CN220751110U discloses a silt thickness detection device, which belongs to the field of detection devices, including a support plate, a detection mechanism, and the entire device is moved to the side of the river where water conservancy engineering construction is required through the universal wheels on the bottom of the T-plate on both sides of the support plate. When detecting the thickness of the silt layer in the river channel, the drive motor is turned on to drive the output end to rotate the screw rod through the rotating rod, so that the movable plate moves downward along the screw rod through the threaded hole, and during the movement, the casing is driven to move downward until it enters the river water, and then the thickness of the silt layer in the river channel is detected by the probe, and the detection result will be transmitted to the ultrasonic mud level meter by the connecting line to display it to the detection personnel, thereby completing the detection operation of the thickness of the silt layer in the river channel, and during the detection, there is no need for the detection personnel to hold the casing for a long time to ensure the stability of the probe during the detection process, and the detection operation saves time and effort.

[0004] However, the detection mechanism of the device is too short to the river surface, which causes many inconveniences during the detection process. For example, there is no suitable placement. In addition, the device uses an electric motor to retract and release the rope, which requires high costs and subsequent maintenance costs, resulting in poor practicality. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2When the lifting device is lifted up, the lifting device 11 is lifted up and the lifting device 12 is lifted up, and the lifting device 12 is lifted and the lifting device 12 is lowered, so that the lifting of the lifting device 12 is realized.

[0032] Reference Figure 1 , Figure 2 A U-shaped block 63 is hinged at the top of the electric push rod 62. The lifting assembly also includes a limiting shell 61. The limiting shell 61 is used to place the rope 8 so that the rope 8 can only move in this area. The U-shaped block 63 is slidably connected to the bottom end of the limiting shell 61. The rope 8 runs through the middle of the limiting shell 61. The bottom end of the limiting shell 61 is fixedly connected to a connecting rod 64, which is used to support the limiting shell 61.

[0033] Reference Figure 1 , Figure 2 The top of the placement shell 2 is fixedly connected with a mounting plate 5, the right side of the mounting plate 5 is set in a semicircular shape, the connecting rod 64 is hinged at the top of the mounting plate 5, and the end of the rope 8 away from the storage roller 3 is fixedly connected with a detector 7.

[0034] Reference Figure 2 - Figure 4 The limiting assembly includes a rectangular shell 41, which is fixedly connected to the front surface of the placement shell 2. The rectangular shell 41 is inclined on the front surface of the placement shell 2. The inner wall of the bottom of the rectangular shell 41 is slidably connected to a trapezoidal block 44. The left side of the bottom of the trapezoidal block 44 is provided with an inclined surface. When the limiting rod 42 rotates with the handle 45, the inclined surface of the trapezoidal block 44 will be squeezed and moved upward. The trapezoidal block 44 and the rectangular shell 41 are elastically connected by a spring 43. The purpose of the spring 43 is to assist the trapezoidal block 44 to reset. One end of the spring 43 is fixedly connected to the inner wall of the rectangular shell 41, and the other end of the spring 43 is fixedly connected to the top of the trapezoidal block 44.

[0035] Reference Figure 2 - Figure 4The outer wall of the rotating rod 4 is slidably connected with a handle 45, and the handle 45 and the rotating rod 4 are elastically connected by a second spring 46. The second spring 46 is used to connect the handle 45, and the reverse force of the second spring 46 assists the handle 45 to reset, so that the limit rod 42 and the trapezoidal block 44 are in the same plane. One end of the second spring 46 is fixedly connected to the front surface of the rotating rod 4, and the other end of the second spring 46 is fixedly connected to the inner wall of the handle 45. The top of the handle 45 is fixedly connected to the limit rod 42.

[0036] Working principle: When in use, first move the device to the place where work is required. When detection is required, pull the handle 45 outward. When the handle 45 is pulled outward, the spring 2 46 will be stretched, and when the handle 45 moves, it will drive the limit rod 42 to move together, so that the limit rod 42 moves out of the bottom end of the trapezoidal block 44 and is not in the same plane with it. At this time, it can be rotated counterclockwise. When the rotating rod 4 rotates, it will drive the storage roller 3 to rotate, so that the rope 8 on the storage roller 3 moves downward through the limiting shell 61, driving the detector 7 to move downward into the water. Carry out inspection. After the rope 8 is placed, slowly loosen the handle 45, and the handle 45 is reset by the reverse force of the spring 2 46, so that the limit rod 42 and the trapezoidal block 44 are in the same plane. At this time, the right-angle surface of the trapezoidal block 44 cooperates with the limit rod 42 to make the rotating rod 4 unable to rotate. When the road surface is uneven and the height of the limiting shell 61 needs to be raised, the electric push rod 62 is started to make the output shaft of the electric push rod 62 move upward, and the output shaft of the electric push rod 62 drives the U-shaped block 63 to slide at the bottom end of the limiting shell 61, thereby adjusting the angle of the limiting shell 61.

[0037] When the detection is completed and the detector 7 needs to be retracted, the handle 45 is directly turned clockwise. When the handle 45 is turned, the rotating rod 4 will be driven to rotate together. When the limiting rod 42 contacts the trapezoidal block 44, it will squeeze the inclined surface of the trapezoidal block 44 to move it upward and squeeze the spring 1 43. After the limiting rod 42 rotates past the trapezoidal block 44, the reverse force of the spring 1 43 resets the trapezoidal block 44, thereby achieving the purpose of one-way limiting, making the work of pulling the detector 7 upward more labor-saving.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
