[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, by incorporating a depth adjustment mechanism, allows for convenient control of the depth to which the drainage tank enters the foundation pit. In actual construction, different foundation pits have varying depths and shapes. By adjusting the screw and threaded sleeve, a motor-driven transmission assembly rotates the screw, thereby raising and lowering the drainage tank. This design enables the device to flexibly adapt to foundation pits of different depths, improving construction flexibility and applicability. Simultaneously, the sliding connection structure between the outer and inner rods further enhances the stability of the drainage tank's raising and lowering process, ensuring smooth construction and effectively avoiding construction problems caused by improper drainage tank positioning, thus improving construction efficiency and quality.
[0014] 2. This utility model achieves efficient and intelligent groundwater drainage by incorporating a pneumatic drainage mechanism. During drainage, an air pump extracts air from the drainage tank through an air pipe, creating a negative pressure state. This draws groundwater from the foundation pit into the drainage tank through the filter assembly. When drainage is needed, the solenoid valve is closed and the air pump is turned on, increasing the air pressure in the drainage tank and propelling the groundwater out through the drainage pipe. This pneumatic drainage method not only boasts high efficiency but also avoids the problem of pump damage caused by prolonged immersion in water in traditional drainage methods, extending the equipment's lifespan. Simultaneously, the filter assembly effectively filters mud and debris from the groundwater, preventing blockages in the drainage pipes and ensuring smooth operation of the drainage system, further improving construction safety and reliability.

[0020] 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.
[0021] Example 1
[0022] Please see Figure 1-4 The present invention provides the following technical solution: a pneumatic dewatering construction device for building foundation engineering, comprising a base 1, a pit 6 inside the base 1, a support plate 3 at the upper end of the base 1, a fixing ear 5 on the side of the support plate 3, the fixing ear 5 being fixedly connected to the base 1 by bolts 4, a drainage box 7 inside the pit 6, a controller 2 at the upper end of the base 1 near the support plate 3, a depth adjustment mechanism 8 at the center of the upper end of the support plate 3, and a pneumatic drainage mechanism 9 on the side of the drainage box 7.
[0023] Specifically, the depth adjustment mechanism 8 includes a screw 81, a threaded sleeve 82, ear plates 83, and a transmission assembly 86. The transmission assembly 86 is located at the upper end of the support plate 3, and the screw 81 is located on one side of the lower end of the transmission assembly 86. The threaded sleeve 82 is threadedly connected to the lower end surface of the screw 81. Two sets of ear plates 83 are located on the upper side of the drainage tank 7, and the lower end of the threaded sleeve 82 is fixed to the upper end of the ear plate 83.
[0024] By adopting the above technical solution, the transmission component 86 can drive the screw 81 to rotate, the rotation of the screw 81 drives the threaded sleeve 82 to rise and fall, and the rise and fall of the threaded sleeve 82 drives the ear plate 83 to rise and fall, thereby controlling the depth of the drainage box 7 entering the pit 6.
[0025] Specifically, the transmission assembly 86 includes a first pulley 861, a motor 862, a mounting box 863, a second pulley 864, and a belt body 865. The mounting box 863 is located at the upper center of the support plate 3. The motor 862 is located on the upper side of the mounting box 863. The first pulley 861 is located at the output end of the motor 862. The second pulley 864 is located inside the mounting box 863 on the upper surface of the screw 81. The belt body 865 is wound around the surfaces of the first pulley 861 and the second pulley 864.
[0026] By adopting the above technical solution, the motor 862 at the top of the mounting box 863 is opened. The motor 862 drives the pulley 861 to rotate through the output end. The rotation of the pulley 861 drives the belt body 865 to rotate. The rotation of the belt body 865 drives the pulley 864 to rotate. The rotation of the pulley 864 drives the screw 81 to rotate.
[0027] Specifically, the depth adjustment mechanism 8 also includes an outer rod 84 and an inner rod 85. The upper end of another set of ear plates 83 is provided with an outer rod 84, and the upper end of the outer rod 84 is slidably connected to the inner rod 85 from the inside to the outside.
[0028] By adopting the above technical solution, when the drainage box 7 is raised or lowered, the inner rod 85 will slide inside the outer rod 84, thereby improving the stability of the raising and lowering process of the drainage box 7.
[0029] In this embodiment, when in use, the motor 862 at the top of the mounting box 863 is turned on. The motor 862 drives the pulley 861 to rotate through the output end. The rotation of the pulley 861 drives the belt body 865 to rotate. The rotation of the belt body 865 drives the pulley 864 to rotate. The rotation of the pulley 864 drives the screw 81 to rotate. The rotation of the screw 81 drives the threaded sleeve 82 to rise and fall. The rise and fall of the threaded sleeve 82 drives the ear plate 83 to rise and fall, thereby controlling the depth of the drainage box 7 entering the pit 6. When the drainage box 7 rises and falls, it will cause the inner rod 85 to slide inside the outer rod 84, thereby improving the stability of the rising and falling process of the drainage box 7.
[0030] Example 2
[0031] The difference between this embodiment and Embodiment 1 is that the pneumatic drainage mechanism 9 includes a filter assembly 91, an air pipe 92, an air pump 93, an air valve 94, and a drain pipe 95. The filter assembly 91 is located at the lower side of the drain tank 7, the drain pipe 95 is located on one side of the upper end of the drain tank 7, the air pipe 92 is located on the other side of the upper end of the drain tank 7, the air pump 93 is located at the other end of the air pipe 92, and the air valve 94 is located on the side of the air pipe 92 near the air pump 93.
[0032] By adopting the above technical solution, when extracting groundwater from the foundation pit 6, the air pump 93 is first turned on, and the air pump 93 extracts the air from the drainage tank 7, so that the drainage tank 7 is in a negative pressure state. At this time, the groundwater in the foundation pit 6 will enter the interior of the drainage tank 7 through the filter component 91. Finally, by injecting air into the drainage tank 7, the air pressure in the drainage tank 7 is greater than the external air pressure, so that the groundwater can be discharged through the drainage pipe 95.
[0033] Specifically, the filter assembly 91 includes a first water inlet pipe 911, a filter box 912, a solenoid valve 913, a second water inlet pipe 914, and a filter plate fixing assembly 915. The filter box 912 is located at the lower side of the drain tank 7. The first water inlet pipe 911 is located on the side of the filter box 912. The filter plate fixing assembly 915 is located inside the filter box 912. The second water inlet pipe 914 is located on the side of the filter box 912 inside the drain tank 7. The solenoid valve 913 is located on the side of the second water inlet pipe 914.
[0034] By adopting the above technical solution, when groundwater enters the drainage tank 7, the groundwater first enters the interior of the filter box 912 through the inlet pipe 1 911, and after being filtered by the filter plate body 9151, it enters the interior of the drainage tank 7 through the inlet pipe 2 914. When the water in the drainage tank 7 is discharged, the solenoid valve 913 is closed and the air pump 93 is turned on. At this time, the air pressure in the drainage tank 7 is greater than the external air pressure, so that the groundwater can be discharged through the drainage pipe 95.
[0035] Specifically, the filter plate fixing assembly 915 includes a filter plate body 9151, a handle 9152, a fixing plate 9153, and a collection box 9154. The filter plate body 9151 is slidably connected inside the filter box 912. The collection box 9154 is located at the lower side of the filter plate body 9151, and the fixing plate 9153 is located at the upper end of the filter plate body 9151. The handle 9152 is located at the upper end of the fixing plate 9153.
[0036] By adopting the above technical solution, pulling the handle 9152 causes the fixing plate 9153 to rise, and the rising of the fixing plate 9153 causes the filter plate body 9151 to slide out from the inside of the filter box 912, at which point the dirt in the collection box 919154 can be cleaned.
[0037] In this embodiment, when pumping out groundwater from the foundation pit 6, the air pump 93 is first turned on. The air pump 93 extracts the air from the drainage tank 7, making the drainage tank 7 under negative pressure. When the groundwater enters the drainage tank 7, it first enters the filter box 912 through the first inlet pipe 911. After being filtered by the filter plate body 9151, it enters the drainage tank 7 through the second inlet pipe 914. When draining the water from the drainage tank 7, the solenoid valve 913 is closed and the air pump 93 is turned on. At this time, the air pressure in the drainage tank 7 is greater than the external air pressure, allowing the groundwater to be discharged through the drainage pipe 95. The handle 9152 is pulled, and the handle 9152 drives the fixing plate 9153 to rise. The rising of the fixing plate 9153 causes the filter plate body 9151 to slide out from the inside of the filter box 912. At this time, the dirt in the collection box 9154 can be cleaned.
[0038] The controller 2 in this utility model is a previously disclosed technology, and the selected model is Siemens S7-1200.
[0039] The air pump 93 in this utility model is a publicly available technology, and the selected model is Deman DM1.5-7.5.
[0040] The working principle and usage process of this utility model are as follows: When using this utility model, the motor 862 at the top of the mounting box 863 is turned on. The motor 862 drives the pulley 861 to rotate through its output end. The rotation of pulley 861 drives the belt body 865 to rotate, which in turn drives the pulley 864 to rotate. The rotation of pulley 864 drives the screw 81 to rotate, which in turn drives the threaded sleeve 82 to rise and fall. The rising and falling of the threaded sleeve 82 drives the ear plate 83 to rise and fall, thereby controlling the depth of the drainage tank 7 entering the foundation pit 6. When the drainage tank 7 rises and falls, the inner rod 85 slides inside the outer rod 84, thus improving the stability of the drainage tank 7 during the rising and falling process. When pumping out groundwater from the foundation pit 6, the air pump 93 is first turned on. Pump 93 extracts air from drainage tank 7, putting it under negative pressure. When groundwater enters drainage tank 7, it first enters filter box 912 through inlet pipe 1 911, is filtered by filter plate body 9151, and then enters drainage tank 7 through inlet pipe 2 914. When draining water from drainage tank 7, solenoid valve 913 is closed and air pump 93 is turned on. At this time, the air pressure in drainage tank 7 is greater than the outside air pressure, allowing groundwater to be discharged through drainage pipe 95. Pull handle 9152, which causes fixed plate 9153 to rise. The rise of fixed plate 9153 causes filter plate body 9151 to slide out from inside filter box 912, allowing the dirt in collection box 9154 to be cleaned.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
