Description

Technical Field

[0001] This utility model relates to the field of sediment collection technology, specifically a device for collecting pollution sources from river and lake sediments. Background Technology

[0002] River and lake sediments are long-term deposits accumulated at the bottom of rivers, lakes, reservoirs, and other water bodies. Their formation is the result of both natural and human activities. Sediments are mainly composed of inorganic solids and organic matter. Inorganic solids include primary minerals, clay minerals, and metal oxides from the soil, while organic matter includes humus, proteins, fats, and polysaccharides.

[0003] In the prior art, a river and lake bottom sediment pollution source collection device with authorization announcement number CN213926444U includes a base, a box fixedly mounted on the upper surface of the base, a sand pump fixedly mounted on the upper surface of the box, a water pumping hose on the left side of the sand pump, and a sand cleaning component on the side of the water pumping hose away from the sand pump. The sand cleaning component includes a shell, a motor is mounted inside the shell, and a spiral stirring tooth is fixedly mounted on the output end of the motor.

[0004] While the above-mentioned solution has many advantages, it also has the following disadvantages: the device directly puts the sand-clearing component into the river and sets up a spiral stirring tooth to stir the silt. However, the spiral stirring tooth is not equipped with a protective structure, which will cause the spiral stirring tooth to come into contact with large fixed objects such as large stones and metal waste in the riverbed. This will cause blockage of the pumping hose and damage to the spiral stirring tooth, thus affecting the service life of the river and lake bottom sediment pollution source collection equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a river and lake bottom sediment pollution source collection device, including a pipe body 1, a fixed outer plate 2 fixedly sleeved at the end of the pipe body 1, a stirring mechanism 3 provided on the fixed outer plate 2, a mesh cover 4 provided at the bottom of the fixed outer plate 2, a cover opening provided at the top of the mesh cover 4, and an installation sleeve 5 provided at the cover opening of the mesh cover 4. The installation sleeve 5 and the fixed outer plate 2 are fixedly connected to each other by bolts. The end of the pipe body 1 away from the fixed outer plate 2 is fixedly connected to the inlet end of a sand pump, and the outlet end of the sand pump is fixedly connected to a box body through a conduit.

[0023] The mesh cover 4 is made of multiple slender metal structures woven and welded together. The metal structures are relatively thin, which reduces the contact area between the mesh cover 4 and the silt. When the stirring mechanism 3 is started, it will vibrate or shake, which makes it easy to sink into the silt by using the weight of the fixed outer plate 2 and itself. The mounting sleeve 5 is fitted on the outside of the fixed outer plate 2. The mounting sleeve 5 has multiple fixing holes on the outside of the mounting sleeve 5. Bolts are inserted into the fixing holes. The fixed outer plate 2 has a fixing groove at the corresponding position of each fixing hole. The bolt surface is provided with external threads, and the inner wall of the fixing groove is provided with internal threads. The bolt is threadedly connected to the internal threads in the fixing groove through the external threads on the outside of the bolt.

[0024] like Figure 1 As shown, a sling 7 is fixedly installed on the upper part of the fixed outer plate 2, a float 6 is installed above the sling 7, and a storage component 8 for storing and releasing the sling 7 is installed on the float 6.

[0025] like Figure 2 As shown, the floating vessel 6 includes two buoyancy airbags 601, and two ventilation airbags 602 are fixedly connected between the two buoyancy airbags 601. An installation plate 603 is installed on the upper part of the ventilation airbag 602, and a through-hole is opened at the center of the upper part of the installation plate 603.

[0026] like Figure 2 As shown, the storage assembly 8 includes a storage rod 801 rotatably connected to the opening, a hanging rope 7 with its top end fixedly wrapped around the outside of the storage rod 801, and a servo motor 802 mounted on the mounting plate 603. The output shaft of the servo motor 802 is fixedly connected to the end of the storage rod 801.

[0027] The outer panel 2 is easily lifted and fixed by the hoisting rope 7 by using the buoyancy airbag 601 on the floating vessel 6 to generate buoyancy.

[0028] The servo motor 802 drives the storage rod 801 to rotate, thereby storing and releasing the hanging rope 7. The fixed outer plate 2 can be lifted by storing the hanging rope 7. When the fixed outer plate 2 needs to be used to clean the silt, it is only necessary to release the hanging rope 7 so that the hanging rope 7 is not in a taut state.

[0029] The servo motor 802 is equipped with a brake structure, which is used to lock and release the output shaft. The brake structure is a prior art device and will not be described in detail in this application.

[0030] like Figure 1 and Figure 2 As shown, a pull rope 9 is installed on one side of the mounting plate 603. A linear array of fixed collars 10 are fitted on the pull rope 9. The output end of the servo motor 802 is electrically connected to a wire 11. Each fixed collar 10 is fixed to the outer wall of the wire 11. The servo motor 802 is electrically connected to the power supply.

[0031] The movable end of the pull rope 9 is fixed to the riverbank, which limits the floating range of the pontoon 6 and allows the pontoon 6 to be pulled back to the bank for easy access to the outer plate 2 and the stirring mechanism 3; the wire 11 is electrically connected to the controller installed on the box, and the controller is electrically connected to the power supply or the battery installed on the box, which provides power to the servo motor 802 and controls the start and stop of the servo motor 802, as well as the forward and reverse rotation of the output shaft of the servo motor 802;

[0032] The controller is an existing technology device, and its specific form, usage and installation location are not described in detail in this application.

[0033] like Figure 1 and Figure 2 As shown, a hanging ring 12 is fixedly connected to one side of the mounting plate 603, and a hook 13 is adapted on the hanging ring 12. A long rod 14 is fixedly installed on one side of the hook 13.

[0034] By using the long pole 14 and the pusher 6, the staff can deploy the fixed outer plate 2 and the mixing mechanism 3 from the shore, and it is also convenient to retrieve the pontoon 6.

[0035] like Figure 4 As shown, the long rod 14 includes a plurality of short rods 141. One end of the short rod 141 and one end of the hook 13 are provided with threaded grooves 143. The other end of the short rod 141 is fixedly connected to a threaded rod 142, which is threaded in the cavity of the threaded groove 143.

[0036] By assembling multiple short rods 141, the length of the long rod 14 can be extended or shortened, thus making it convenient to adjust the length of the long rod 14 according to the actual needs on site, and at the same time, it is convenient to store the long rod 14.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
