Description

Technical Field

[0001] The utility model relates to the field of sewage cleaning, in particular to a municipal convenient drainage ditch sludge cleaning device. Background Art

[0002] Municipal drainage ditches have important functions and roles in urban construction, and play an irreplaceable role in ensuring the normal operation of the city, improving the quality of the urban environment, and protecting urban infrastructure. Drainage ditches are mainly used to collect and discharge rainwater and domestic sewage. In actual use, as time accumulates, silt and debris will settle and adhere to the drainage ditch, affecting the drainage work of the drainage ditch and even causing the drainage network to be blocked. Therefore, it is necessary to regularly remove the silt in the drainage ditch. In order to facilitate the removal of silt and debris in the drainage ditch, the applicant proposed a municipal convenient drainage ditch silt cleaning equipment to facilitate staff to quickly clean the drainage ditch. Utility Model Content

[0003] In order to solve the technical problem of conveniently cleaning the sludge and debris in the drainage ditch, the utility model provides a municipal convenient drainage ditch sludge cleaning device.

[0004] The utility model is implemented by the following technical scheme: a municipal portable drainage ditch sludge cleaning device, comprising a mobile trolley, the mobile trolley is connected with:

[0005] A mounting platform, the mounting platform being fixedly connected to the front end of the mobile vehicle;

[0006] A lifting plate, the lifting plate is arranged below the mounting platform;

[0007] A silt-clearing plate, which is fixedly mounted below the lifting plate, and has side plates with variable angles on both sides of the silt-clearing plate;

[0008] A control component is installed in the installation platform and is used to control the lifting movement of the lifting plate.

[0009] Through the above technical scheme, the lifting plate and the silt cleaning plate are first driven downward by the control component and enter the drainage ditch, so that the bottom of the silt cleaning plate is in contact with the bottom surface of the drainage ditch as much as possible, and the mobile cart moves along the direction of the drainage ditch. The silt cleaning plate and the side plates with variable angles on both sides clean the drainage ditch together, and the silt and debris in the drainage ditch are collected for centralized cleaning.

[0010] As a further improvement of the above solution, the control component includes:

[0011] A rotating drum, the rotating drum is rotatably mounted on the mounting platform, the upper part of the rotating drum extends out of the mounting platform, and an internal thread is provided on the inner wall of the rotating drum;

[0012] A pulley, a motor is also installed in the mounting platform, one end of the motor is connected to a pulley, and the pulley and the rotating drum are connected by a belt;

[0014] As a further improvement of the above solution, support frames are fixedly connected to both sides of the bottom of the mounting platform, pulleys are installed at the bottom of the support frames, and a guide rod is fixedly connected to the middle of the support frames.

[0015] As a further improvement of the above solution, limit plates are fixedly connected to both sides of the lifting plate, and the limit plates are sleeved on the outside of the guide rod.

[0016] Through the above technical solution, when the motor drives the drum to rotate through the pulley, since the control shaft and the drum are threadedly connected, the control shaft, the lifting plate and the limit plate are fixedly connected, and the limit plate can only move up and down along the guide rod, the control shaft can only move up and down and cannot rotate. When the drum rotates forward and reverse, the control shaft can be driven to move up and down through the control shaft and the threads on the inner wall of the drum.

[0017] As a further improvement of the above solution, the upper end of the silt cleaning plate is fixedly connected to the lifting plate, a leakage hole is provided on the silt cleaning plate, and a conical silt cleaning claw is fixedly connected to the bottom of one side of the silt cleaning plate.

[0018] Through the above technical solution, the leakage hole is used to filter sewage, the front end of the dredging claw is sharp, and the upper end surface is inclined, which is convenient for penetrating into the silt and is used to remove stubborn silt in the drainage ditch.

[0019] As a further improvement of the above solution, two side plates are provided and are symmetrically rotatably mounted on one side of the dredging plate, and a retaining spring is connected between the side plate and the dredging plate.

[0020] As a further improvement of the above solution, scraping teeth are provided on one side of the silt cleaning plate.

[0021] Through the above technical solution, the angle of the side plate can be changed, which is convenient for application to drainage ditches of different widths and sizes, and can avoid hard contact between the side plate and the inner wall of the drainage ditch, which may cause damage.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The utility model controls the silt removal plate to move downward into the drainage ditch through the control component. When the mobile trolley moves along the drainage ditch, the silt removal plate pushes the silt and debris inside the drainage ditch together for centralized treatment. At the same time, the conical silt removal claws and side plates at the front end of the silt removal plate facilitate the removal of attachments on the inner wall of the drainage ditch. At the same time, the angle of the side plate is variable, so there is no need to worry about the side plate and the inner wall of the drainage ditch being in hard contact and causing damage to the side plate when the mobile trolley shakes and deviates. The service life and safety of the side plate are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0030] Please combine Figure 1 - Figure 4 The embodiment of the municipal portable drainage ditch sludge cleaning device includes a mobile trolley 1. First, the mobile trolley 1 can be driven by an operator to travel along the drainage ditch. This is an existing device. The drainage ditch sludge cleaning device shown in this embodiment only needs to be connected to the front end of the mobile trolley 1 through a connecting frame (not marked in the figure) and screws.

[0031] The front end of the mobile trolley 1 is fixedly connected to the mounting platform 2 through a connecting frame, and the two sides of the bottom of the mounting platform 2 are fixedly connected to the supporting frame 5, and the bottom of the supporting frame 5 is provided with a pulley. When the mobile trolley 1 moves along the drainage ditch, the pulley moves along the two sides of the drainage ditch.

[0032] A lifting plate 3 is provided at the bottom of the mounting platform 2, and a dredging plate 8 for dredging is fixedly connected to the lower end surface of the lifting plate 3. Because there may be water in the drainage ditch during the dredging process, a leakage hole 9 is provided on the dredging plate 8, and when the dredging plate 8 moves along the drainage ditch, water can pass through the leakage hole 9. The silt impurities are intercepted by the dredging plate 8. In addition, in order to prevent the silt in the drainage ditch from being attached to the drainage ditch due to a long sedimentation time and being difficult to remove, a triangular pyramid-shaped dredging claw 10 is fixedly welded on one side of the dredging plate 8. The front end of the dredging claw 10 is sharp, and the upper two sides are inclined, which is convenient for piercing into the silt, shoveling the silt, and removing stubborn silt.

[0033] On the other hand, in order to facilitate the cleaning of the inner wall of the drainage ditch at the same time, a side plate 11 is rotatably connected to the side of the silt removal plate 8 opposite to the silt removal claw 10, and a retaining spring 12 is directly installed on the side plate 11 and the silt removal plate 8. In addition, a scraping tooth 13 is arranged at the edge of the side plate 11 close to the inner wall of the drainage ditch.

[0034] In the initial state, the clip 12 pushes the side plate 11 to rotate and unfold, and the scraper teeth 13 on the edge of the side plate 11 will contact the inner wall of the gutter, and the attachments on the inner wall will be cleaned during the movement. Since the gutter is generally supported by concrete or stone, there is no need to worry about the scraper teeth 13 damaging the gutter.

[0035] Definition Figure 3 The state shown is the unfolded state of the side plate 11, and the side plate 11 compresses the retaining spring 12 and folds it inside the dredging plate 8 to be the retracted state;

[0036] By compressing the retaining spring 12, the unfolded length of the side plate 11 can be controlled. On the one hand, it can be applied to drains of different widths, that is, the side plate 11 can be manually controlled to rotate and retract before the dredging plate 8 enters the drain. When the dredging plate 8 is located inside the drain, the retaining spring 12 automatically pushes the side plate 11 to rotate, so that the side plate 11 contacts the side wall of the drain, which is convenient for cleaning the side wall of the drain. On the other hand, since the above description requires the trolley to move along the drain, it is impossible for the mobile trolley 1 to move smoothly in actual use, and there will be shaking or offset. When this happens, the side plate 11 can be retracted (or partially retracted) by compressing the retaining spring 12, so there is no need to worry about the side plate 11 being damaged due to hard contact between the side plate 11 and the inner wall of the drain when the mobile trolley 1 shakes or deviates. The service life and safety of the side plate 11 are improved.

[0037] In order to facilitate the placement of the silt removal plate 8 and the lifting plate 3 into the drainage ditch, a control component 4 is provided on the mounting platform 2, and the control component 4 is used to drive the lifting plate 3 to move up and down. The specific control component 4 includes a rotating drum 41. First, the rotating drum 41 and the mounting platform 2 are rotatably connected through a bearing. Secondly, the upper half of the rotating drum 41 extends out of the mounting platform 2 and is provided with a belt groove. A motor (not marked in the figure) is installed inside the mounting platform 2, and a pulley 42 is connected to one end of the motor, and the pulley 42 and the rotating drum 41 are connected by a belt. That is, the motor drives the rotating drum 41 to rotate through the pulley 42 and the belt. In addition, the control component 4 also includes a control shaft 43, which is a threaded shaft and runs through the rotating drum 41 as a whole. The corresponding inner wall of the rotating drum 41 is provided with an internal thread, and the rotating drum 41 and the control shaft 43 are threadedly connected. The bottom of the control shaft 43 is fixedly connected to the upper surface of the lifting plate 3. In addition, in actual use, the top of the control shaft 43 is fixedly connected to a limit baffle (not marked in the figure) to prevent the control shaft 43 from exceeding the stroke and detaching from the rotating drum 41.

[0038] In addition, in order to control the lifting and lowering of the lifting plate 3, limit plates 7 are fixedly connected on both sides of the lifting plate 3, holes are opened on the limit plates 7, and guide rods 6 are fixedly installed on the support frame 5, and the limit plates 7 are sleeved on the outside of the guide rods 6. Therefore, the lifting plate 3 (limit plates 7) is supported to move up and down along the guide rods 6.

[0039] To sum up, the control shaft 43, the lifting plate 3 and the limit plate 7 are fixedly connected, so they can only move up and down. Therefore, when the motor and the pulley 42 control the rotation of the rotating drum 41, the control shaft 43 will be driven to move up and down, so it can also drive the lifting plate 3 and the silt removal plate 8 installed under the lifting plate 3 to move downward, thereby entering the interior of the drainage ditch.

[0040] The implementation process and principle of a municipal portable drainage ditch sludge cleaning device in the embodiment of the present application are as follows:

[0041] (I): The staff drives the mobile trolley 1 to the drainage ditch to be cleaned, controls the pulley 42 to rotate through the motor, and drives the rotating drum 41 to rotate through the belt. Because the control shaft 43 can only be lifted and moved but cannot be rotated, when the rotating drum 41 rotates forward and backward, the control shaft 43 will drive the lifting plate 3 to move up and down together, and the limit plate 7 and the guide rod 6 provide a limit and guide function.

[0042] When the lifting plate 3 moves downward, it is convenient to put the silt removal plate 8 into the gutter, so that the bottom of the silt removal plate 8 contacts the bottom of the gutter. At this time, the two support frames 5 are located on both sides of the gutter.

[0043] (II): When the mobile vehicle 1 moves along the drainage ditch, the pulleys under the support frame 5 move along the two sides of the drainage ditch, and when the silt removal board 8 moves along the drainage ditch, water can pass through the leakage hole 9. The silt impurities are intercepted by the silt removal board 8. At the same time, the front end of the silt removal claw 10 is sharp, and the upper two sides are inclined, which is convenient for piercing into the silt, shoveling the silt, and removing stubborn silt.

[0044] The angle of the side plate 11 can be changed by compressing the clip 12, and the unfolded length of the side plate 11 can be controlled by compressing the clip 12. On the one hand, it can be applied to drains of different widths, and it is convenient to clean the side wall of the drain with the scraper 13; on the other hand, the side plate 11 can be retracted (or partially retracted) by compressing the clip 12, so there is no need to worry about the side plate 11 and the inner wall of the drain being in hard contact and causing damage to the side plate 11 when the mobile trolley 1 shakes or deviates. The service life and safety of the side plate 11 are improved.

[0045] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
