Description

Technical Field

[0001] This utility model relates to the field of water area detection technology, specifically to a water conservancy telescopic measuring rod. Background Technology

[0002] In the construction, maintenance, and water resource monitoring of water conservancy projects, it is often necessary to measure water areas, including depth detection and heavy metal detection in riverbeds. Traditional measuring tools present many inconveniences. Ordinary measuring rods have a fixed length, making it difficult to adapt to the measurement needs of water areas with different depths. If the length is too long, it is inconvenient to carry. Some adjustable-length measuring rods have complex structures, are inconvenient to operate, and have poor stability, easily wobbling during measurement and affecting measurement accuracy.

[0003] In addition, riverbed samples need to be extracted when testing riverbed composition. The aforementioned measuring rods often do not have the function of riverbed sampling, and additional equipment is required for sampling, which increases the number of tools carried by staff and increases their burden. Utility Model Content

[0004] The purpose of this utility model is to provide a water conservancy telescopic measuring rod to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a water conservancy telescopic measuring rod, including an inner tube, an outer tube slidably connected to the surface of the inner tube, and a fixing component between the outer tube and the inner tube for fixing the relative position of the inner tube and the outer tube;

[0007] The lower end of the inner tube is threaded with a sampling component for picking up riverbed samples;

[0008] The outer tube is equipped with a striking component for striking the outer tube downwards, causing the outer tube to drive the sampling component to be inserted into the riverbed for sampling.

[0009] The above-mentioned water conservancy telescopic measuring rod is used to pull the inner tube out of the outer tube so that the lengths of the inner and outer tubes are superimposed to meet the length requirements for insertion into the water body. Then, the inner tube and the outer tube are fixed by the fixing component. The inner tube and the outer tube are inserted into the water body so that the sampling component comes into contact with the riverbed. Then, the outer tube is knocked down by the tapping component to insert the sampling component into the riverbed. The riverbed sample can be picked up by the sampling component.

[0010] Preferably, the sampling assembly includes a sleeve, the upper end of which is threaded to the lower end of the inner tube. Two flaps are rotatably connected inside the sleeve, and the two flaps cooperate to seal the sleeve. A stop block is fixedly connected to the inner wall of the sleeve to support the flaps and prevent them from flipping downwards.

[0011] Preferably, the lower end of the sleeve is designed with a chamfer.

[0012] Preferably, the flap is semi-circular, with the two flaps facing each other. The flap has a notch, and a fixing rod is fixedly connected inside the notch. A connecting plate is rotatably connected to the fixing rod, and the connecting plate is fixedly connected to the inner wall of the sleeve.

[0013] Preferably, a torsion spring is fitted on the surface of the fixing rod, and the two ends of the torsion spring are fixedly connected to the flap and the inner wall of the sleeve, respectively.

[0014] Preferably, a baffle is fixedly connected to the lower end of the inner tube, a handle is fitted on the surface of the outer tube, and scale lines for displaying length are provided on the surfaces of both the inner and outer tubes.

[0015] Preferably, the fixing component includes a spring pin, which is fixedly connected to the outer tube. The inner tube has several locking holes along a straight line, and the spring pin passes through the outer tube and is inserted into the locking holes.

[0016] Preferably, the striking assembly includes two fixing plates fixed to the surface of the outer tube. A counterweight is slidably connected to the surface of the outer tube and is located between the two fixing plates. A handle is fixedly connected to the counterweight, and a shock-absorbing pad is fixedly connected to the upper side of the fixing plate located below the counterweight.

[0017] The beneficial effects are:

[0018] 1. By superimposing the lengths of the inner and outer tubes, the required length for insertion into the water body can be met. Overlapping the inner and outer tubes can shorten the length of the device, making it easy to carry. The inner and outer tubes can be fixed by the fixing component. The inner and outer tubes are inserted into the water body, allowing the sampling component to be inserted into the riverbed. The sampling component can pick up riverbed samples for riverbed composition detection. The sampling steps are simple and easy to operate, which can effectively reduce the workload of staff.

[0019] 2. By tapping the outer tube downwards with the tapping component, the sampling component can be inserted into the riverbed more easily. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-6 As shown, this utility model provides a water conservancy telescopic measuring rod, including an inner tube 1, an outer tube 2 slidably connected to the surface of the inner tube 1, and a fixing component 3 between the outer tube 2 and the inner tube 1 for fixing the relative position of the inner tube 1 and the outer tube 2.

[0031] The lower end of the inner tube 1 is threaded with a sampling component 8, which is used to pick up riverbed samples;

[0032] The outer tube 2 is equipped with a striking component 6 for striking the outer tube 2 downwards, causing the outer tube 2 to drive the sampling component 8 to be inserted into the riverbed for sampling.

[0033] As an optional implementation, the sampling assembly 8 includes a sleeve 15, the upper end of which is threadedly connected to the lower end of the inner tube 1. Two flaps 16 are rotatably connected inside the sleeve 15. The two flaps 16 cooperate to block the sleeve 15. A stop block 17 is fixedly connected to the inner wall of the sleeve 15 to support the flaps 16 and prevent the flaps 16 from flipping downward.

[0034] During the process of inserting the sleeve 15 into the riverbed, the two flaps 16 flip upwards, and the riverbed soil enters the sleeve 15. When the sleeve 15 is pulled out from the riverbed, the two flaps 16 flip downwards, but can only flip to a horizontal state. The two flaps 16 and the two blocks 17 work together to block the soil sample into the sleeve 15, preventing the soil sample from flowing out of the sleeve 15.

[0035] Rotate the sleeve 15 to disengage it from the lower end of the inner tube 1, and then pour out the soil sample from the sleeve 15.

[0036] The lower end of the sleeve 15 is designed with a chamfer, which makes it easier to insert the sleeve 15 into the riverbed.

[0037] The flap 16 is semi-circular, with the two flaps 16 facing each other. A notch is provided on the flap 16, and a fixing rod 18 is fixedly connected inside the notch. A connecting plate 20 is rotatably connected to the fixing rod 18, and the connecting plate 20 is fixedly connected to the inner wall of the sleeve 15.

[0038] A torsion spring 19 is sleeved on the surface of the fixing rod 18. The two ends of the torsion spring 19 are fixedly connected to the flap 16 and the inner wall of the sleeve 15, respectively. The torsion spring 19 is used to reset the flap 16, so that the flap 16 flips downward to a horizontal state.

[0039] A baffle 7 is fixedly connected to the lower end of the inner tube 1. The baffle 7 is set to prevent the inner tube 1 from being inserted too deeply into the riverbed. The baffle 7 can significantly increase the resistance of the inner tube 1 when inserted into the riverbed, which can be clearly perceived by the staff. A handle 5 is fitted on the surface of the outer tube 2. Both the inner tube 1 and the outer tube 2 are provided with scale lines 4 for displaying the length.

[0040] The fixing component 3 includes a spring pin 13, which is fixedly connected to the outer tube 2. Several locking holes 14 are opened along the straight line on the inner tube 1. The spring pin 13 passes through the outer tube 2 and is inserted into the locking holes 14. The length of the inner tube 1 and the outer tube 2 can be adjusted and fixed by the cooperation of the spring pin 13 and the several locking holes 14.

[0041] The striking component 6 includes two fixing plates 11, which are fixed to the surface of the outer tube 2. A counterweight 9 is slidably connected to the surface of the outer tube 2, and the counterweight 9 is located between the two fixing plates 11. A handle 10 is fixedly connected to the counterweight 9, and a shock-absorbing pad 12 is fixedly connected to the upper side of the fixing plate 11 below the counterweight 9.

[0042] By moving the counterweight 9 upwards using the handle 10, it strikes the lower fixing plate 11, creating a downward impact force that causes the sampling component 8 to be fully inserted into the riverbed.

[0043] Using the above structure, the inner tube 1 is pulled out from the outer tube 2, so that the lengths of the inner tube 1 and the outer tube 2 are superimposed to meet the length requirements for insertion into the water body. Then, the inner tube 1 and the outer tube 2 are fixed by the fixing component 3, and the inner tube 1 and the outer tube 2 are inserted into the water body so that the sampling component 8 comes into contact with the riverbed. Then, the outer tube 2 is knocked down by the striking component 6 so that the sampling component 8 is inserted into the riverbed. The riverbed sample can be picked up by the sampling component 8.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
