Description

Technical Field

[0001] The present invention relates to the technical field related to bottom mud collection, and in particular to a bottom mud collection device and a collection method with high stability. Background Art

[0002] The bottom sediment of a river often plays the role of the source and sink of pollutants in the river water. When the concentration of pollutants accumulated in the bottom sediment of a river is higher than that of the overlying water body, the pollutants will be gradually released into the water body, causing the water body to be polluted again, increasing the difficulty of water treatment. Therefore, as an endogenous pollution of water bodies, the pollution of bottom sediment of a water body has attracted more and more attention. During the treatment process, the staff needs to collect the bottom sediment in the river through a bottom sediment collection device and analyze the pollution of the bottom sediment. For example, a natural river surface bottom sediment collection device proposed by a Chinese invention with the authorization announcement number CN104502146B includes a main frame, a bracket, a sampling rod and a sampling head, the main frame is arranged on the bracket, the sampling rod is installed on the main frame, and the sampling head is connected to one end of the sampling rod; the main frame includes a fixed seat, a sleeve and a sleeve moving mechanism, the sleeve is arranged on the fixed seat, the sleeve is connected to the sleeve moving mechanism, and positioning clamps are arranged at both ends of the sleeve; the bracket includes legs, a force plate and a connecting frame; the sampling head includes a sampling box, a push-pull sleeve rod, a rotating rod and a sampling valve. First, connect the main frame to the bracket, and fix the bracket on the ground; adjust the length of the sampling rod, pass the sampling rod through the sleeve in the main frame, and connect the sampling head to the top of the sampling rod; move the sampling rod forward through the sleeve moving mechanism to drive the sampling head to operate and collect mud. This device realizes the long-distance surface sediment collection, makes the sampling positioning accurate, saves time and effort, and is easy to carry. It is suitable for collecting surface sediment in shallow rivers; In order to prevent the bottom mud from falling when the collection device is raised, a blocking structure is set in the collection device, such as a lake bottom mud collection device proposed in the Chinese invention with the authorization announcement number CN115389253B, which is used to be arranged on a ship, and includes a lifting device, a sampling rod, a cylindrical sampling body and a sampling head connected in sequence, a collection chamber with a downward opening is provided in the cylindrical sampling body, a collection channel that can be connected to the collection chamber is provided in the sampling head, a valve plate and a rotating part are provided in the collection channel, and the rotating part drives the valve plate to rotate in the collection channel to have a first working position corresponding to the insertion process of the sampling head and a second working position corresponding to the sampling process of the sampling head. In the first working position, the valve plate is parallel to the axial section of the cylindrical sampling body, and in the second working position, the valve plate and the axial section of the cylindrical sampling body form a blocking angle. The lake bottom mud collection device provided by the present invention can prevent the collected object from falling during the ascending sampling process, ensure the amount of bottom mud collected each time, reduce the number of collection times, and improve the efficiency of bottom mud collection work; However, the existing sediment collection devices still have the following problems: A valve plate is provided in the collection channel. During the lake sediment collection process, the valve plate forms a blocking structure in the collection channel to prevent the collected material from falling. However, the valve plate is provided in the collection channel, which will affect the amount of sediment collected and the sediment entering the collection channel, and it is not convenient to seal the collection structure. The bottom mud is collected in the collection structure, and it is inconvenient to unload it from the collection structure during unloading. Therefore, we propose a high-stability bottom mud collection device and collection method to solve the above problems. Summary of the invention

[0003] To solve the problems raised in the above background technology. The present invention provides a highly stable bottom mud collection device and collection method, which has the characteristics of adjusting the length of the device by selecting the number of first extension rods to be installed, adapting to different water depths, preventing the mud inside the collection mechanism from falling off during the lifting process, having high stability during the collection process, and pushing the collected mud out from the inside of the porous rubber bag, which is convenient for material collection.

[0004] To achieve the above object, the present invention provides the following technical solution: a highly stable sediment collection device, comprising a mounting mechanism, a lifting mechanism and a collection mechanism: The mounting mechanism comprises a mounting frame, a slide groove, a base and screw holes, the front and rear ends of the mounting frame are provided with slide grooves, the bottom end of the mounting frame is fixed with a base, the inside of the base is provided with screw holes, and the rear end of the mounting frame is fixed with a motor; A lifting mechanism is installed on the inner side of the mounting mechanism, and the lifting mechanism includes a gear plate and a rack. The output end of the motor is fixed with a gear plate, and the right end of the gear plate is meshed and connected with the rack. A first extension rod is arranged below the lifting mechanism, and a second extension rod is installed at the bottom end of the first extension rod, and a chassis is installed at the bottom end of the second extension rod. An operating rod runs through the interior of the chassis, and a push plate is fixed on the lower surface of the operating rod. A collecting mechanism is installed at the bottom end of the chassis, and the collecting mechanism includes a first mounting ring, a porous rubber bag and a second mounting ring. The porous rubber bag is fixed to the lower surface of the first mounting ring, and the second mounting ring is fixed to the bottom end of the porous rubber bag. A waterproof electric telescopic rod is fixed at an equal angle to the lower surface of the chassis, and a bottom ring is fixed to the output end of the waterproof electric telescopic rod, and an insert ring is fixed to the lower surface of the bottom ring. A collecting groove is opened inside the bottom ring, and a sealing mechanism is installed on the bottom ring. The sealing mechanism includes a motor, a baffle, a winding roller, a wire groove and a sealing rope. A motor is fixedly installed inside the collecting groove, a baffle is fixed to the output end of the motor, and a winding roller is fixed at the end of the baffle away from the motor. The winding roller is rotatably installed in the bottom ring, and the end of the sealing rope is fixed to the outer side of the winding roller. A wire groove opened in the bottom ring is arranged above the collecting groove.

[0005] By adopting the above technical solution, the length of the device is adjusted by selecting the number of first extension rods to be installed to adapt to different water depths, thereby preventing the soil inside the collecting mechanism from falling off during the lifting process. The collection process has high stability, and the collected soil is pushed out from the inside of the porous rubber bag to facilitate material collection.

[0006] As a preferred technical solution of the present invention, the outer end of the rack is located inside the slide groove.

[0007] By adopting the above technical solution, since the outer end of the rack is located inside the slide groove, the movement trajectory of the rack is limited by the slide groove.

[0008] As a preferred technical solution of the present invention, the bottom end of the rack is inserted into the top end of the first extension rod, and the first extension rod is fixedly connected to the rack by screws.

[0009] By adopting the above technical solution, since the first extension rod is fixedly connected to the rack by screws, it is easy to disassemble and assemble the first extension rod and the rack.

[0010] As a preferred technical solution of the present invention, the bottom end of the first extension rod is inserted into the top end of the second extension rod, and the first extension rod is fixedly connected to the second extension rod by screws.

[0011] By adopting the above technical solution, since the first extension rod is fixedly connected to the second extension rod by screws, it is convenient to disassemble and assemble the first extension rod and the second extension rod.

[0012] As a preferred technical solution of the present invention, the diameter of the push plate is the same as the vertical distance between the left and right inner walls of the first mounting ring.

[0013] By adopting the above technical solution, since the diameter of the push plate is the same as the vertical distance between the left and right inner walls of the first mounting ring, the outer side surface of the push plate fits against the inner wall of the first mounting ring. When the push plate is pushed, the outer side surface of the push plate can clean the inner wall of the first mounting ring.

[0014] As a preferred technical solution of the present invention, the connection modes of the first mounting ring and the chassis, and the connection modes of the second mounting ring and the bottom ring are both threaded connections.

[0015] By adopting the above technical solution, since the connection between the first mounting ring and the chassis and the second mounting ring and the bottom ring are both threaded connections, it is convenient to disassemble and assemble the first mounting ring and the chassis and the second mounting ring and the bottom ring.

[0016] As a preferred technical solution of the present invention, the upper surface of the second mounting ring is flush with the upper surface of the bottom ring.

[0017] By adopting the above technical solution, since the upper surface of the second mounting ring is flush with the upper surface of the bottom ring, the sealing rope is prevented from being located on the second mounting ring.

[0018] A collection method of a high-stability sediment collection device comprises the following steps: Step 1: Select the number of first extension rods to be installed according to the water level of the river, thereby adjusting the length of the device, and adjusting the length of the collection mechanism according to the required bottom mud depth; Step 2: lowering the collecting mechanism through the lifting mechanism so that the collecting mechanism is inserted into the soil to collect riverbed mud; Step 3: Seal the opening at the bottom of the collection mechanism through the sealing mechanism to prevent the soil from falling and stably collect the bottom mud; Step 4: Raise the collecting mechanism under the action of the lifting mechanism to take the material.

[0019] Compared with the prior art, the invention has the following beneficial effects: by selecting the number of first extension rods installed to adjust the length of the device, it can adapt to different water depths, prevent the soil inside the collection mechanism from falling off during the lifting process, and provide high stability during the collection process, and push the collected soil out of the porous rubber bag to facilitate material collection; 1. The first extension rod is connected with the second extension rod by screws, and the first extension rod is connected with the first extension rod by screws. The length of the device can be adjusted by selecting the number of first extension rods to adapt to different water depths. 2. After the collecting mechanism is inserted into the soil and the bottom mud is collected, the bottom end of the collecting mechanism is tightened by the sealing mechanism to prevent the soil inside the collecting mechanism from falling during the ascending sampling process and improve stability. The sealing mechanism is located outside the collecting mechanism. When the collecting mechanism falls to collect the bottom mud, the sealing mechanism does not affect the collection of the collecting mechanism; The porous rubber bag inside the collection mechanism is used to store the bottom mud. Since the porous rubber bag contains many tiny holes, it can filter water during the collection and lifting process, reduce the lifting resistance of the collection mechanism, and facilitate the discharge of most of the water in the bottom mud; 3. After taking the collecting mechanism out of the water, untie the sealing rope inside the sealing mechanism, open the opening at the bottom of the porous rubber bag, push the operating rod and the push plate downward, and push the collected soil out of the porous rubber bag to facilitate material collection. The inner wall of the porous rubber bag can be cleaned during the downward movement of the push plate; The distance between the chassis and the bottom ring is adjusted under the action of the waterproof electric telescopic rod, thereby adjusting the depth of the collected soil and collecting soil at different depths. During the discharging process, the distance between the chassis and the bottom ring is shortened by the waterproof electric telescopic rod to facilitate discharging.
