Description

Technical Field

[0001] This utility model belongs to the field of river water exploration technology, and in particular relates to a river water resource exploration device. Background Technology

[0002] River water resource exploration equipment is a device used to explore and measure various resources and hydrological parameters in rivers. It is mainly used in water resource management, flood control and drought relief and environmental protection. It includes water level gauges, current meters, flow meters, water quality monitoring instruments, radar hydrological monitoring stations, sampling equipment and water drilling equipment, which can meet the diverse needs of river resource exploration.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing river water resource exploration devices:

[0004] 1. When the exploration sampling tube is used to sample the silt at the bottom of the river, it is impossible to cut off the connection between the silt inside the sampling tube and the silt outside the sampling tube. This can easily cause the silt inside the sampling tube to fall out when it is lifted. It is not convenient to install cutting measures on the sampling tube to prevent the silt inside the sampling tube from falling out due to adhesion.

[0005] 2. The exploration sampling tube achieves sampling by drawing samples through the negative pressure generated by pulling the piston rod. However, due to accidental operation, the piston rod may move, causing the sludge that has been sampled inside the sampling tube to be discharged. It is not convenient to install lifting measures on the sampling tube to allow the piston rod to move up and down through engagement. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a river water resource exploration device. This device solves the problem that existing exploration sampling cylinders, when sampling riverbed silt, cannot cut off the connection between the silt inside and outside the sampling cylinder, easily causing the silt inside the sampling cylinder to detach during lifting. It is inconvenient to install cutting measures on the sampling cylinder to prevent the silt from sticking and detaching. Furthermore, the exploration sampling cylinder uses negative pressure generated by pulling the piston rod to draw samples, which is prone to accidental movement of the piston rod, causing the sampled silt inside the sampling cylinder to be discharged. It is also inconvenient to install lifting measures on the sampling cylinder to allow the piston rod to move up and down through engagement.

[0007] The purpose and effectiveness of this utility model river water resource exploration device are achieved through the following specific technical means:

[0008] A river water resource exploration device includes a device body; the device body is provided with an exploration sampling tube, and both ends of the exploration sampling tube have threaded annular grooves on their outer circumferences. A contact protective cylinder is threadedly installed at the lower end of the exploration sampling tube. The top of the contact protective cylinder has a threaded annular groove on its inner circumference. The front and rear walls of the contact protective cylinder are provided with strip holes with left and right through holes. The left and right sides of the outer circumference of the contact protective cylinder are provided with vertically penetrating wire rings. The bottom outer circumference of the contact protective cylinder is provided with a conical surface. A cutting steel wire rope is installed between the strip holes of the contact protective cylinder through a fixed shaft. Both ends of the cutting steel wire rope are provided with left and right fixed cylinders.

[0009] Furthermore, a lifting piston rod is threadedly mounted on the threaded rod of the lifting piston rod. A threaded blind hole is opened on the top end face of the lifting piston rod, a regular hexagonal groove is opened on the bottom end face of the lifting piston rod, an annular groove is opened on the outer circumference of the lifting piston rod, and a rubber cylinder is installed inside the annular groove of the lifting piston rod.

[0010] Furthermore, a lifting piston rod is installed inside the lifting rotary cylinder by threads. The outer circumference of the lifting piston rod is threaded, and a vertically oriented strip groove is formed at the front of the outer circumference of the lifting piston rod. A regular hexagonal prism is provided on the bottom end face of the lifting piston rod, and a threaded post is provided on the bottom end face of the regular hexagonal prism of the lifting piston rod.

[0011] Furthermore, a lifting rotating cylinder is installed inside the bearing groove of the lifting bearing cylinder via a bearing. The inner circumference of the lifting rotating cylinder is threaded, and the outer circumference of the lower end of the lifting rotating cylinder is provided with a bearing ring groove. A handle rod is provided at both the front and rear of the outer circumference of the lifting rotating cylinder.

[0012] Furthermore, a fixed anti-rotation post is installed inside the threaded hole of the lifting bearing cylinder, a threaded post is provided behind the fixed anti-rotation post, a limit ring plate is provided on the outer circumference of the front end of the threaded post of the fixed anti-rotation post, and a regular hexagonal prism is provided on the front end face of the threaded post of the fixed anti-rotation post.

[0013] Furthermore, the upper end of the exploration sampling tube is threaded with a lifting bearing cylinder. The bottom of the lifting bearing cylinder has a threaded annular groove on its inner circumference. The outer circumference of the lifting bearing cylinder has a hanging column with a top through groove on both sides in the middle of the front. The outer circumference of the lifting bearing cylinder has a handle rod on both the left and right sides. The top end face of the lifting bearing cylinder has a bearing block with upper and lower through holes. The top end face of the bearing block of the lifting bearing cylinder has a bearing groove. The lower part of the front wall of the bearing block of the lifting bearing cylinder has a threaded hole.

[0014] Furthermore, a rope sealing ball is installed inside the threading ring of the contact protective cylinder. A sealing ball is set at the upper end of the rope sealing ball, and a hanging rope with a hanging ring is set at the top of the sealing ball. Closed-loop pull ropes are set on the lower left and right sides of the sealing ball, and a handle is set in the middle of the lower end of the closed-loop pull rope of the rope sealing ball.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The convenient cutting wire rope is installed on the contact protection cylinder via a fixed shaft, allowing the device body to be rotated 180 degrees to cut the silt. This solves the problem that when sampling riverbed silt, it is impossible to cut the connection between the silt inside and outside the sampling cylinder, which can easily cause the silt inside the sampling cylinder to fall out when it is lifted. It is also inconvenient to install cutting measures on the sampling cylinder to prevent the silt inside the sampling cylinder from falling out due to adhesion.

[0017] The convenient lifting and rotating cylinder is mounted on the lifting support cylinder via bearings to support the lifting piston rod. The lifting piston rod drives the lifting piston column to rise and fall through threaded engagement. This solves the problem that the exploration sampling cylinder, which uses the negative pressure generated by pulling the piston rod to extract samples, is prone to accidental movement of the piston rod due to malfunction, causing the sludge collected inside the sampling cylinder to be discharged. It is also inconvenient to add lifting measures to the sampling cylinder to allow the piston rod to rise and fall through engagement. Attached Figure Description

[0028] The lifting bearing cylinder 6 has a fixed anti-rotation post 7 installed inside its threaded hole to prevent the lifting piston rod 9 from rotating. A threaded post is located behind the fixed anti-rotation post 7 for easy installation via threads.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, such as Figure 1 As shown, the device body 1 is in a placed state. At this time, the rope sealing ball 5 is hung on the hanging column of the lifting bearing cylinder 6, and the lifting piston rod 9 is retracted into the exploration sampling tube 2. This facilitates the lifting, moving, and storage of the device body 1. Figure 1As shown, when the device body 1 is conducting exploration and sampling, hold the handle of the lifting support cylinder 6, align the contact protection cylinder 3 with the silt, remove the rope sealing ball 5 from the hanging column of the lifting support cylinder 6, and pull the handle of the rope sealing ball 5 upwards to the middle position of the exploration and sampling tube 2 to prevent the handle of the rope sealing ball 5 from being buried by the silt. Insert the contact protection cylinder 3 vertically into the silt at the bottom of the river, rotate the lifting rotating cylinder 8 to engage with the lifting piston rod 9 through the threaded engagement, so that the lifting piston rod 9 rises through the threaded engagement. The lifting piston rod 9 drives the lifting piston column 10 to rise synchronously along the inside of the exploration and sampling tube 2, so that the rubber sleeve of the lifting piston column 10 forms a dynamic seal with the inner wall of the exploration and sampling tube 2, thereby generating a negative pressure inside the exploration and sampling tube 2 below the lifting piston column 10, continuously pumping the silt sample. The sludge is drawn into the exploration sampling tube 2. This method solves the problem that the exploration sampling tube, which uses negative pressure generated by pulling the piston rod to draw in sludge, is prone to accidental piston rod movement, causing the sampled sludge to be discharged from the sampling tube. After the sludge is drawn in, the device body 1 is rotated 180 degrees, and the wire rope 4 is simultaneously cut off, thus cutting off the sludge. This solves the problem that when the exploration sampling tube is sampling riverbed sludge, it is impossible to cut off the connection between the sludge inside and outside the sampling tube, which can easily cause the sludge inside the sampling tube to fall out when it is lifted. Then, the handle of the rope sealing ball 5 is pulled upward to the top of the exploration sampling tube 2 and the tension is maintained, so that the sealing ball of the rope sealing ball 5 blocks the opening at the lower end of the contact protective tube 3, as shown in the figure. Figure 6 As shown, the device body 1 can be lifted out of the water body at this time, thereby completing the silt sampling for river water resource exploration.

[0031] Example 2: The difference from Example 1 is that the regular hexagonal groove of the lifting piston column 10 can also be set as a regular heptagonal groove, so that the lifting piston column 10 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the lifting piston column 10.

[0032] Example 3: The difference from Example 1 is that the regular hexagonal prism of the fixed anti-rotation column 7 can also be set as a regular heptagonal prism, so that the fixed anti-rotation column 7 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the fixed anti-rotation column 7.
