[0024] In order to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.
[0025] Figure 1 is a structural diagram of a low water level water pumping and draining device in a structure provided by an embodiment of the present application, Figure 2 is Figure 1 a sectional view. Referring to Figure 1 and Figure 2 , the present application provides a low water level water pumping and draining device in a structure, which comprises an outer shell 1, the bottom of the outer shell 1 is open, a sewage pump 2 is fixedly installed on the inner wall top of the outer shell 1, and the water outlet of the sewage pump 2 penetrates the top of the outer shell 1.
[0026] One end of a water injection pipe 3 is fixedly connected to the top of the outer shell 1, and the water injection pipe 3 is communicated with the inside of the outer shell 1.
[0027] A plurality of slot holes 4 are formed in the bottom of the outer shell 1 around, the slot holes 4 are uniformly distributed and communicated with the inside of the outer shell 1.
[0028] It should be noted that the outer shell 1 and the sewage pump 2 are welded, and the water injection pipe 3 and the outer shell 1 are welded, and full welding is adopted during welding, so as to ensure firm connection and good sealing at the connection.
[0029] The diameter of the water injection pipe 3 is 50 mm.
[0030] The water outlet of the sewage pump 2 is connected to a drain pipe, which is not shown in the figure.
[0031] It is easy to understand that the water inlet of the sewage pump 2 is relatively close to the bottom surface of the outer shell 1 without protruding out of the outer shell 1.
[0032] The use process is as follows: the sewage pump 2 is connected to a power supply circuit, the device is placed in water at a relatively low position on the boundary line of the structure, water is injected into the outer shell 1 through the water injection pipe 3, the sewage pump 2 is started after the water injection is stopped after the outer shell 1 is filled with water, and the water in the outer shell 1 is pumped out, a low pressure state is formed in the outer shell 1, so that the water outside the outer shell 1 automatically flows into the inside of the outer shell 1, and then is pumped out to the outside of the structure by the sewage pump 2.
[0033] In the above embodiment, the siphon principle is used to quickly pump out the accumulated water in the structure, without the need to frequently move the device. The accumulated water in the structure flows to the device, which greatly reduces the amount of residual water in the structure, improves the water pumping efficiency, and has a simple structure, is reusable, is economically applicable, and has no noise and environmental pollution hazards.
[0034] In some examples, the water injection pipe 3 is provided with a valve 5.
[0035] It is easy to understand that the water injection pipe 3 includes a first water injection pipe and a second water injection pipe. The lower end of the first water injection pipe is firmly connected to the top of the shell 1 by full welding. The upper end of the first water injection pipe is firmly connected to one end of the valve 5 by screwing or full welding. The other end of the valve 5 is connected to the lower end of the second water injection pipe by screwing or full welding. The upper end of the second water injection pipe is connected to a water source. The length of the first water injection pipe and the second water injection pipe is 100 mm, and the diameter is 50 mm.
[0036] In the above embodiment, the valve 5 can quickly realize the on-off of the water injection pipe 3. The water injection pipe 3 is divided into two parts, the first water injection pipe and the second water injection pipe. Such segmented design not only facilitates installation and maintenance, but also improves the flexibility and adaptability of the device to a certain extent.
[0037] Further, the valve 5 can be a spherical valve.
[0038] Referring to Figure 2 In some examples, the inner wall of the shell 1 is fixedly connected to one end of at least one support rod 6 around the periphery, and the other end of the support rod 6 is fixedly connected to the outer periphery of the sewage pump 2.
[0039] It should be noted that the number of support rods 6 is 8, which are evenly distributed in the shell 1, and the two ends are respectively welded to the middle of the shell 1 and the bottom of the sewage pump 2.
[0040] Further, the support rod 6 can be a φ14mm steel bar.
[0041] In the above embodiment, the shell 1 and the sewage pump 2 are connected by multiple support rods 6, which can enhance the stability of the sewage pump 2, effectively prevent it from shaking or moving during operation, and thus ensure that the sewage pump 2 can continuously and stably output power to complete the task of pumping and discharging sewage. Moreover, it can stably support the shell 1 to prevent the shell 1 from being depressed due to external air pressure or water pressure when it enters a low pressure or even near-vacuum state, thereby improving the structural strength of the shell 1. The multiple support rods 6 are evenly distributed in the shell 1, and the stress is more uniform, which is beneficial to prolong the service life of the support rod 6 and the shell 1.
[0042] In some examples, the shell 1 comprises a top plate 11 with a central opening and four isosceles trapezoidal plates 12, the top plate 11 is fixedly connected with the top of the isosceles trapezoidal plates 12 respectively, and adjacent two isosceles trapezoidal plates 12 are fixedly connected;
[0043] The top plate 11 is sleeved on the water outlet of the sewage pump 2 and fixedly connected therewith, and the water injection pipe 3 is arranged at the eccentric position of the top plate 11.
[0044] One end of the support rod 6 is fixedly connected with the corresponding isosceles trapezoidal plate 12, and the slot hole 4 is arranged at the bottom of the isosceles trapezoidal plate 12.
[0045] It should be noted that the top plate 11 and the isosceles trapezoidal plate 12 are fully welded. The top plate 11 is a square structure, a φ5cm hole is formed at any position of the top plate 11 which is 5cm away from the sewage pump 2 and the corner, and the first water injection pipe is fully welded at the hole.
[0046] In the above embodiment, a relatively closed and solid space is formed by the top plate 11 and the isosceles trapezoidal plate 12 for accommodating the sewage pump 2 and other necessary components. The center of the top plate 11 is provided with an opening which can match the water outlet of the sewage pump 2, so as to realize the close and stable connection between the top plate 11 and the water outlet of the sewage pump 2, which not only ensures that the sewage can flow out of the shell 1 smoothly from the sewage pump 2, but also enhances the stability of the sewage pump 2 in the shell 1 through the fixing effect of the top plate 11. The slot hole 4 is arranged at the bottom of the isosceles trapezoidal plate 12, that is, at the bottom of the device, and the sewage at the position of the device can flow into the shell 1 through the slot hole 4, which is beneficial to reduce the sewage residue in the structure.
[0047] In some examples, the cross section of the slot hole 4 is semicircular, and the diameter of the slot hole 4 is
[0048] In the formula, D is the diameter of the water outlet of the sewage pump 2.
[0049] It is easy to understand that the size of the slot hole 4 is determined according to the size of the water outlet of the sewage pump 2, so as to ensure that the water inflow of the shell 1 matches or is slightly larger than the water outflow of the sewage pump 2, so as to ensure the normal operation of the sewage pump 2.
[0050] In some examples, the number of the slot holes 4 at the bottom of each isosceles trapezoidal plate 12 is 3-5.
[0051] In some specific examples, the number of the slot holes 4 at the bottom of each isosceles trapezoidal plate 12 is 4.
[0052] In the process of cleaning the silt and garbage under the shallow water level of the built structure such as concrete or masonry (for example, the stilling basin, the water storage tank and the sewage tank), due to the fact that the water collecting well cannot be used for pumping and draining in the structure, and the conventional sewage pump is relatively high and large, the pumping and draining effect is poor, and the dry working environment cannot be created, resulting in low efficiency of cleaning the silt and garbage.
[0053] In view of the above problems, the embodiment of the present application provides a shallow water level pumping and draining device in a structure, which is composed of a shell 1, a sewage pump 2, a water injection pipe 3, a slot hole 4, a valve 5 and a supporting rod 6. According to the design of the concrete or masonry structure, combined with the actual situation on site, the device is fixed and sealed to connect the drainage hose and the power supply line by the construction personnel, and then the device is placed at the relatively low part of the structure boundary line. The shell 1 is filled with water through the water injection pipe 3, the air in the shell 1 is emptied, then the valve 5 is closed and the sewage pump 2 is started, and the sewage in the shell 1 can be pumped out of the structure by the sewage pump 2. As the water in the shell 1 decreases, the shell 1 enters a low pressure or even a vacuum state, and the structure stability of the shell 1 is maintained by the supporting rod 6 to prevent the shell 1 from being damaged and depressed under the action of external pressure. The sewage in the structure flows to the device, which is conducive to reducing the load of the sewage pump 2, thereby reducing the energy consumption of the sewage pump 2. Under the action of siphon, the sewage far from the device in the structure automatically flows into the shell 1 through the slot hole 4, and the pumping and draining efficiency is higher. The position of the device does not need to be frequently moved, and it is especially suitable for pumping and draining the water in the shallow water level of the structure. The water inlet of the sewage pump 2 cannot be submerged under water, thereby reducing or even avoiding the damage and burning of the sewage pump 2 caused by sucking air. A dry working environment can be quickly created for the construction personnel to clean the remaining garbage in the structure.
[0054] It is easy to understand that, based on the several embodiments provided by the present application, the skilled in the art can combine, split, recombine and obtain other embodiments of the present application, which do not exceed the protection scope of the present application.

It should be understood that the above is only a specific embodiment of the present application, and is not used to limit the protection scope of the embodiments of the present application.
