[0013] 1. The filter screen is connected in a magnetic attraction mode, so that the filter screen can be quickly disassembled and replaced, and great operation convenience and efficiency are provided without affecting the sealing performance of the water collecting tank. This design is particularly suitable for environments where the filter screen needs to be frequently cleaned or replaced. The magnetic attraction steps and the iron frame ensure that the filter screen is stably fixed in the rectangular opening and can be easily disassembled, so that maintenance personnel can quickly clean or replace the filter screen without using tools. In addition, the plastic waterproof layer on the outer side of the iron frame further enhances the stability and durability of the structure, effectively prevents corrosion caused by long-term contact with water, and prolongs the service life of the equipment.
[0014] 2. The hook and the slag receiving basket are arranged, so that the slag removed by the scraper can be collected, thereby simplifying the slag cleaning process, improving the cleaning efficiency, and keeping the drainage system unobstructed. The slag receiving basket is hung on the hook on the cover plate through the hanging hole, so that when the scraper moves along the screw rod, the slag attached to the inner wall of the water collecting tank can be scraped into the slag receiving basket. The drainage hole in the slag receiving basket allows water to flow out smoothly, and only large solid particles are retained, which not only helps to protect the water pump from damage by large particles, but also significantly reduces the risk of blockage. This design also reduces the need for manual intervention, making the entire system more automated and efficient.
[0015] 3、By introducing the lead screw device to drive the movement of the scraper, the automatic and uniform cleaning function of the water collecting tank is realized, so that the long-term stable operation of the equipment is ensured, the maintenance cost is reduced and the reliability of the system is improved. The reduction motor in the lead screw device provides power, so that the lead screw rotates and drives the sliding block through the lead screw nut, and then pushes the connecting plate and the scraper to move linearly along the guide bar. This mechanism ensures that the scraper can effectively cover the entire inner wall of the water collecting tank to remove the deposits that may affect the drainage efficiency. Especially for such special environment as the civil air defense basement, regular and effective cleaning is one of the key factors to maintain the normal operation of the system. Therefore, this design not only improves the quality of cleaning work, but also reduces the work burden of maintenance personnel.

DETAILED DESCRIPTION
[0023] In order to further understand the utility model content, characteristics and functions of the present application, the following examples are given, and the detailed description is as follows in conjunction with the drawings.
[0024] As shown in Figures 1 to 5 , the present application provides a civil air defense basement drainage device.
[0025] The water collecting tank 4 is provided with a cover plate 2, the upper part of the cover plate 2 is clamped with a heightened box body 1, the front side and the rear side of the heightened box body 1 are provided with slag discharge ports 11, the inside of the heightened box body 1 is provided with a lead screw device 7 for driving the scraper 8 to move, the middle part of the cover plate 2 is provided with a rectangular opening 21, the inside of the rectangular opening 21 is provided with a magnetic attraction step 22, the upper part of the magnetic attraction step 22 is connected with a filter screen 5, the outside of the filter screen 5 is fixedly connected with an iron frame 51, the front side and the rear side of the cover plate 2 are fixedly connected with hooks 24, the hooks 24 are connected with a slag receiving basket 6, and the right side of the water collecting tank 4 is connected with a drainage pump 3.
[0026] A plurality of drainage holes 61 are formed in the slag receiving basket 6, and a hook hole 62 for connecting with the hook 24 is formed in the slag receiving basket 6.
[0027] The lower part of the drainage pump 3 is connected with a water inlet pipe 31, the water inlet pipe 31 extends into the inside of the water collecting tank 4, and the upper part of the drainage pump 3 is connected with a drainage pipe joint 32.
[0028] The upper part of the cover plate 2 is fixedly connected with a water guide plate 23, and the outside of the iron frame 51 is fixedly connected with a plastic waterproof layer.
[0029] The lead screw device 7 comprises a speed reducer motor 74, the output shaft of the speed reducer motor 74 is fixedly connected with a lead screw 71, the lead screw 71 is drivingly connected with a sliding block 72 through a lead screw nut, the lower part of the sliding block 72 is fixedly connected with a connecting plate 73, and the connecting plate 73 is connected with the scraper 8 through bolts.
[0030] The left side and the right side of the scraper 8 are respectively provided with notched grooves 81, and the inside of the cover plate 2 is fixedly connected with guide strips 82.
[0031] Working principle: when the civil air defense basement needs to be drained, the user first ensures that the water collecting tank 4 is in normal working condition, and the heightened box body 1 has been correctly installed on the cover plate 2. At this time, the water inlet pipe 31 of the drainage pump 3 is deeply inserted into the inside of the water collecting tank 4 to prepare for water pumping operation, and the drainage pipe joint 32 is connected to the external drainage system.
[0032] As underground water or rainwater flows into the water collecting tank 4, the water flow will gather in the rectangular opening 21. In this process, the filter screen 5 fixedly arranged on the magnetic attraction step 22 in the rectangular opening 21 will intercept larger solid particles and sundries. The iron frame 51 is tightly attached to the magnetic attraction step 22 by magnetic force, which ensures good sealing performance and facilitates quick disassembly, cleaning or replacement.
[0033] Once the lead screw device 7 is started, the deceleration motor 74 begins to operate and drives the lead screw 71 to rotate. The lead screw 71 is transmitted to the sliding block 72 through the lead screw nut, so that the sliding block 72 moves linearly along the lead screw 71. The connecting plate 73 below the sliding block 72 in turn pushes the scraper 8 to move along the guide bar 82, and the notch groove 81 on the scraper 8 ensures that it will not be hindered during movement. With the movement of the scraper 8, it can effectively remove the deposits and other impurities attached to the filter screen 5 and push them to the vicinity of the slag discharge port 11, and finally fall into the slag receiving basket 6. The several drainage holes 61 on the slag receiving basket 6 allow water to continue to flow, while larger solid particles are retained for subsequent treatment.
[0034] When the slag receiving basket 6 is full, the user can easily remove the slag receiving basket 6 for cleaning through the hook 24. Since the slag receiving basket 6 is designed in a form that can be easily disassembled, this greatly simplifies the maintenance process and reduces the time and complexity of manual intervention. After cleaning, the normal operation of the equipment can be restored by hanging the hook 24 back.
[0035] Throughout the process, the drainage pump 3 continues to operate, drawing water from the sump tank 4 through the water inlet pipe 31 and discharging it to the outside or designated drainage point through the drainage pipe joint 32. This process ensures that even in the event of flooding or other emergencies in the underground space, the accumulated water can be effectively drained in time to ensure the safety of the civil defense basement.
[0036] In summary, the civil defense basement drainage device of the present application not only realizes efficient drainage function, but also greatly improves the reliability and maintainability of the system through a series of automation and humanization design, and is suitable for various occasions that may encounter sudden large amount of water.
[0037] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
