[0021] For reference Figures 1-4 As shown, according to the embodiments of the present application, a ground alpha radioactive contamination efficient cleaning and decontamination and waste liquid recovery device is provided, comprising: A cleaning disc shell 1 is provided with a cleaning cavity inside; A cleaning assembly 2 is arranged in the cleaning cavity, for cleaning the ground facing the cleaning cavity; A radioactive waste liquid recovery assembly 3 comprises a recovery fixing frame 31, which is arranged on both sides of the cleaning disc shell 1 along the first direction and located in the cleaning cavity, and the recovery fixing frame 31 is provided with a recovery cavity on the side facing the ground; The cleaning assembly 4 comprises a first cleaning part 41 and a second cleaning part 42, the first cleaning part 41 comprises a first brush strip 411 and a first water blocking strip 412, the first brush strip 411 and the first water blocking strip 412 are distributed along the length direction of the recovery cavity and are located on both sides of the recovery cavity, and the first water blocking strip 412 is located on the side of the recovery fixed frame 31 away from the washing cavity; the second cleaning part 42 is arranged on the washing disc shell 1 in a second direction perpendicular to the first direction, the second cleaning part 42 comprises a second brush strip 421 and a second water blocking strip 422, and the second water blocking strip 422 is located on the side of the second brush strip 421 away from the washing cavity. The brush density of the first brush strip 411 is greater than the brush density of the second brush strip 421.

[0022] The ground alpha radioactive pollution efficient cleaning and decontamination and waste liquid recovery device provided by the embodiment of the application is remotely operated by an operator through a remote control system to complete the cleaning and decontamination operation, the device comprises a washing disc shell 1, a washing assembly 2, a radioactive waste liquid recovery assembly 3 and a cleaning assembly 4, the washing cavity in the washing disc shell 1 provides a space for ground cleaning operation to avoid the diffusion of radioactive pollutants in the cleaning process; the washing assembly 2 outputs a cleaning medium in the washing cavity to realize the cleaning of the contaminated ground; the radioactive waste liquid recovery assembly 3 can quickly collect the radioactive waste liquid generated in the cleaning through the recovery cavity formed in the recovery fixed frame 31 after the cleaning is completed; the cleaning assembly 4 can further block the leakage of pollutants and assist in improving the decontamination effect through the first cleaning part 41 and the second cleaning part 42, realizes the efficient decontamination of the nuclear industrial scene, and can minimize the secondary pollution risk caused by radioactive waste liquid and dust, and is suitable for different cleaning working conditions of different pollution degrees and different ground materials.

[0023] The cleaning assembly 2 is arranged in the cleaning cavity. According to the type of ground pollution, the cleaning medium suitable for the ground pollution is output, and the cleaning medium directly acts on the polluted ground facing the cleaning cavity. Compared with the traditional open cleaning, the closed space of the cleaning cavity can constrain the diffusion range of the cleaning medium, avoid radioactive substances splashing to the non-polluted area with the cleaning medium, and ensure that the force of the cleaning assembly 2 is concentrated on the polluted surface, thereby improving the decontamination efficiency per unit area. Especially for the stubborn radioactive pollutants in the nuclear industry scene, the output intensity of the cleaning assembly 2 can be increased (such as increasing the high-pressure water pressure) to achieve deep decontamination. In the radioactive waste liquid recovery stage, the recovery fixing frame 31 of the radioactive waste liquid recovery assembly 3 is arranged on both sides of the cleaning disc shell 1 along the first direction (such as the length direction of the cleaning disc shell 1) and located in the cleaning cavity. The first cleaning element 41 and the second cleaning element 42 of the cleaning assembly 4 are distributed along the first direction and the second direction (such as the width direction of the cleaning disc shell 1) perpendicular to each other. The first brush strip 411 and the second brush strip 421 can block part of the splashed radioactive waste liquid and dust. The first water blocking strip 412 and the second water blocking strip 422 further intercept the pollutants penetrating the brush strip. In addition, the bristle density of the first brush strip 411 is greater than that of the second brush strip 421, which can strengthen the leakage prevention effect of the periphery of the recovery cavity. The high-density first brush strip 411 can reduce the overflow of radioactive waste liquid from both sides of the recovery cavity through the more dense bristle gaps.

[0024] It can be understood that the bristle density of the first brush strip 411 is greater than that of the second brush strip 421. When the cleaning assembly 2 outputs high-pressure water to impact the ground, the splashed radioactive waste liquid and various solid particles will be intercepted by the first brush strip 411 and the second brush strip 421. The first brush strip 411 has a higher bristle density and a stronger adsorption capacity for the high-concentration waste liquid around the recovery cavity. Under the action of the negative pressure of the radioactive waste liquid recovery assembly 3, the radioactive waste liquid and particles adsorbed by the first brush strip 411 will quickly flow into the recovery cavity along the connecting part between the root panel and the bristles, and then be transported to the special treatment equipment through the recovery pipe 32, thereby avoiding the secondary penetration pollution caused by the retention of radioactive waste liquid on the ground.

[0025] The first brush strip 411 and the second brush strip 421 are in uniform contact with the ground. The splashed radioactive waste liquid and solid particles generated during the cleaning process are first blocked and isolated by the first brush strip 411 and the second brush strip 421 around them. A small amount of penetrating pollutants will be secondarily isolated by the first water blocking strip 412 and the second water blocking strip 422 on the outside, thereby avoiding the diffusion of radioactive substances to the environment outside the cleaning cavity.

[0026] During the cleaning process, radioactive waste liquid and various loose solid particles inevitably remain on the ground in the cleaning tray shell 1. At this time, the first brush strip 411 and the second brush strip 421 will be in continuous contact with the ground as the cleaning tray moves. Under the action of the negative pressure generated in the recovery fixed frame 31 by the vacuum pump, the residual pollutants will be re-adsorbed in the first brush strip 411 vertical direction, and finally flow into the recovery cavity for recovery.

[0027] The first water baffle 412 and the second water baffle 422 have sufficient structural strength, and the bottom thereof maintains a reasonable compression force with the ground determined by experiments. When the vacuum pump is started, the first water baffle 412 and the second water baffle 422 are closely attached to the ground to quickly form a closed space, so that the cleaning cavity and the periphery of the recovery cavity quickly reach a sufficient negative pressure value. During the movement of the cleaning tray, the elastic deformation capability of the first water baffle 412 and the second water baffle 422 can adapt to the changes in the flatness of the ground, and always maintain a reasonable compression force with the ground to avoid negative pressure leakage, thereby ensuring that the functions of brush strip adsorption, residual cleaning, radioactive waste liquid recovery, etc. always operate stably.

[0028] In a feasible implementation, the radioactive waste liquid recovery assembly 3 further comprises: A recovery pipe 32, which is connected to the recovery fixed frame 31 through the cleaning tray shell 1.

[0029] In this technical solution, the recovery pipe 32 is connected to the recovery fixed frame 31 through the cleaning tray shell 1. By connecting the recovery pipe 32 to the external vacuum pump, the vacuum pump provides negative pressure power to vacuumize the recovery cavity, thereby quickly extracting the radioactive waste water generated during cleaning, and avoiding the retention of waste water in the recovery cavity.

[0030] In a feasible implementation, the second cleaning member 42 further comprises a limiting plate 423, which is arranged on the cleaning tray shell 1 and located in the cleaning cavity. The second brush strip 421 and the second water baffle 422 are arranged on the limiting plate 423.

[0031] In this technical solution, the limiting plate 423 is installed on the cleaning tray shell 1 to fix the second brush strip 421 and the second water baffle 422.

[0032] In a feasible implementation, a camera is arranged above the rear side of the cleaning tray shell 1 to observe the ground environment during the cleaning operation.

[0033] In the technical scheme, the camera is installed on the upper side of the rear side of the cleaning disc shell 1, so that a wide range of visual observation of the cleaned ground is realized. When the cleaning assembly 2 completes the ground cleaning, the cleaning disc shell 1 moves, the camera visually observes the cleaning area, quickly identifies whether there is obvious stain residue on the ground, preliminarily judges the cleaning and stain removal effect and the waste liquid recovery effect from the physical layer, and the operator can remotely observe the walking road condition of the device.

[0034] It can be understood that the camera adopts a miniaturized radiation-resistant camera, which can resist the splashing of radioactive waste liquid in the cleaning process and the radiation erosion in the nuclear environment, and ensure long-term stable operation.

[0035] In a feasible implementation, a fixing assembly 5 is arranged between the recovery fixing frame 31 and the cleaning disc shell 1. The fixing assembly 5 comprises: A clamping ring 51 is arranged on the cleaning disc shell 1. A clamping block 52 is arranged on the recovery fixing frame 31. A connecting piece is arranged between the clamping ring 51 and the clamping block 52.

[0036] In the technical scheme, the fixing assembly 5 arranged between the recovery fixing frame 31 and the cleaning disc shell 1 further improves the connection stability between the recovery fixing frame 31 and the cleaning disc shell 1. The fixing assembly 5 comprises the clamping ring 51, the clamping block 52 and the connecting piece. The clamping ring 51 is installed on the cleaning disc shell 1. The clamping block 52 can be clamped into the clamping ring 51 during installation. The connecting piece is used to connect the clamping block 52 and the clamping ring 51 after installation, so as to stably fix the recovery fixing frame 31, and further stably support the first brush strip 411 and the first water blocking strip 412.

[0037] The connecting piece is a buckle or a bolt.

[0038] In a feasible implementation, the cleaning assembly 2 comprises: A connecting pipe 21 is arranged on the cleaning disc shell 1. A spraying pipe 22 is arranged on the connecting pipe 21 and located in the cleaning cavity. A high-pressure nozzle 23 is arranged on the spraying pipe 22.

[0039] A clamping piece is arranged between the connecting pipe 21 and the cleaning disc shell 1.

[0040] In the technical solution, the cleaning assembly 2 comprises a connecting pipe 21, a spraying pipe 22, high-pressure nozzles 23 and a clamping piece. The spraying pipe 22 is arranged on the connecting pipe 21 and located in the cleaning cavity, and is made of the same corrosion-resistant alloy material as the connecting pipe 21. The spraying pipe 22 is usually linear, grid-shaped or annularly distributed in the cleaning cavity to ensure that the entire area to be cleaned can be covered. The spraying pipe 22 and the connecting pipe 21 are connected by a quick connector or a threaded connection mode, which is convenient for disassembly and maintenance, and ensures the sealing of the connection to prevent leakage of the cleaning medium. In actual work, after the high-pressure water or chemical reagent is delivered to the spraying pipe 22 through the connecting pipe 21, the spraying pipe 22 can uniformly distribute the cleaning medium to each high-pressure nozzle 23.

[0041] The clamping piece arranged between the connecting pipe 21 and the cleaning disc shell 1 is usually composed of two half-ring-shaped clamping bodies, which are fastened to the connecting pipe 21 by bolts or buckles. The inner wall of the clamping piece is provided with an antiskid rubber pad, which can increase the friction between the connecting pipe 21 and the clamping piece, prevent displacement of the connecting pipe 21 during work, and avoid damage to the surface of the connecting pipe 21. During installation, the clamping piece can be adjusted according to the pipe diameter of the connecting pipe 21 to ensure close fitting, facilitate disassembly and reinstallation, and facilitate maintenance and repair of the equipment. The presence of the clamping piece not only enhances the stability of the connection between the connecting pipe 21 and the cleaning disc shell 1, but also effectively reduces noise and loosening risk caused by vibration during cleaning.

[0042] The cleaning disc shell 1 is provided with a walking support 6.

[0043] In a feasible implementation, the walking support 6 comprises: An L-shaped fixed plate 61 arranged on the cleaning disc shell 1; A universal wheel 62 arranged on the L-shaped fixed plate 61.

[0044] In the technical solution, the walking support 6 comprises an L-shaped fixed plate 61 and a universal wheel 62. One plate surface of the L-shaped fixed plate 61 is tightly fixed to the top of the cleaning disc shell 1 by means of bolts, welding or riveting, etc., to ensure that it will not be loose or displaced during operation of the device. The other plate surface serves as a mounting carrier for the universal wheel 62, which ensures that the universal wheel 62 can stably bear the overall weight of the device after installation and maintain balance during movement.

[0045] In practical applications, when the surface of different areas in the nuclear facility needs to be cleaned and decontaminated, the operator can drive the movement and lifting of the device by remotely controlling the crawling robot at the rear end of the device, and use the universal wheels 62 of the walking support 6 to easily move the device to the target position. The stable support of the L-shaped fixed plate 61 ensures that the device does not shake or tilt during movement, ensuring the safety of the internal components. After reaching the designated position, start the cleaning assembly 2, sewage recovery component and other components to start the cleaning and decontamination operation. During the cleaning and decontamination operation, the cleaning disc shell 1 can be pushed to move horizontally along the ground by the universal wheels 62, and the first brush strip 411 and the second brush strip 421 move with the shell to generate friction with the ground, achieving brushing cleaning of residual contaminants and improving cleaning efficiency. During the cleaning process, the bottom of the first brush strip 411, the first water barrier strip, the second brush strip 421 and the second water barrier strip 422 can be in close contact with the ground to ensure the leak-proof function.

[0046] In the above, the bottom of the universal wheel 62 is slightly higher than the bottom of the first brush strip 411, the first water barrier strip 412, the second brush strip 421 and the second water barrier strip 422, which can realize that the bottom of the first brush strip 411, the first water barrier strip 412, the second brush strip 421 and the second water barrier strip 422 can be in full contact with the surface of the equipment to be cleaned during the pushing process.

[0047] In a feasible implementation, the cleaning disc shell 1 is provided with a mounting groove for connecting the driving component.

[0048] In this technical solution, the ground alpha radioactive contamination efficient cleaning and decontamination and waste liquid recovery device is integrally installed at the front end of the vacuum adsorption crawling robot with a lifting device at the rear end. During operation, according to the set working mode, the robot moves to the target operation area in remote control or autonomous mode, lowers the device to the ground, and under the action of the vacuum adsorption disc at the rear end of the crawling robot, the cleaning disc and the cleaning assembly are pressed to the operation ground to form a closed operation grid area, and then the cleaning and decontamination operation is started. The device can be quickly realized according to the needs of the site to adapt to the characteristics of different operation areas.

[0049] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application should be included in the protection scope of the present application. The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, which should be regarded as the protection scope of the present application.
