Description

Technical Field

[0001] The present invention belongs to the technical field of drainage equipment, and in particular relates to a drainage hose cleaning mechanism and a water supply and drainage device for a deep foundation pit. Background Art

[0002] A deep foundation pit refers to a foundation pit with an excavation depth of 5 meters or more, or a basement with three or more floors, or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment, and underground pipelines. Currently, the water supply and drainage systems used for deep foundation pits generally include a submersible pump and a pipe connected to the submersible pump. When draining a deep foundation pit, water is pumped by placing a submersible pump inside the pit. In existing water supply and drainage systems, the submersible pump and pipe are typically rigidly connected, and the diameters of the submersible pump and pipe are generally not uniform. To facilitate the connection of submersible pumps of different specifications to pipes, a drainage hose is typically connected between the submersible pump and pipe. However, during the drainage process, clay residue may remain in the hose. Long-term accumulation of clay in the hose not only causes the hose walls to stick together but also leads to clogging. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a drainage hose cleaning mechanism which is convenient for cleaning the clay remaining in the drainage hose.

[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: a drainage hose cleaning mechanism includes a water pipe, one end of the water pipe is a hose connecting end, and a drainage hose is fixedly connected to the hose connecting end; an annular groove is provided on the hose connecting end of the water pipe, which is located in the drainage hose, and a receiving groove is provided on the inner end surface of the annular groove; a cleaning ring is provided in the annular groove, and a support rod connected to the cleaning ring is provided in the receiving groove; an adjustable limiting component is provided on the water pipe, and when the adjustable limiting component is in a limiting position, it can prevent the support rod from moving along its own axial direction; a spring is also provided in the receiving groove, and the spring is located between the inner end surface of the receiving groove and the inner end of the support rod; when the support rod is in the receiving groove and is restricted by the adjustable limiting component, the spring is in a compressed state; when the adjustable limiting component leaves the limiting position, the spring changes from the compressed state to a natural state, and pushes the support rod to move along its own axial direction, and the cleaning ring is driven by the support rod to move from one end of the drainage hose toward the other end thereof.

[0005] Furthermore, two centrally symmetrical receiving grooves are provided on the inner end surface of the annular groove.

[0006] Furthermore, a limiting groove is provided on the support rod, a through hole connected to the receiving groove is provided on the water pipe, and the adjustable limiting component includes a pin arranged in the through hole; when the adjustable limiting component is in the limiting position, the pin is inserted into the limiting groove to limit the support rod.

[0007] Furthermore, the adjustable limiting component also includes an elastic button arranged on the outer wall of the water pipe, and the pushing end of the elastic button is fixedly connected to the outer end of the latch.

[0008] Furthermore, the elastic button is covered with an anti-slip cover with anti-slip grooves.

[0009] Furthermore, a button spring is provided between the pushing end of the elastic button and the outer wall surface of the water pipe, and the button spring is in a stretched state.

[0010] Furthermore, a spherical groove is provided on the inner end of the latch, and a ball is rotatably provided in the spherical groove.

[0011] Furthermore, a limit block is provided on the outer wall of the support rod near the inner end of the support rod, and the limit block corresponds horizontally to the limit end of the adjustable limit component.

[0014] The beneficial effects of the present invention are as follows: by adjusting the adjustable limit component to move it away from the limit position, the spring can be changed from a compressed state to a natural state, and the support rod can be pushed to move outward along its own axis, thereby causing the cleaning ring to be driven by the support rod from one end of the drain hose to the other end thereof, thereby cleaning the residual clay in the drain hose and unblocking the hose wall stuck by the clay. By providing an annular elastic airbag on the outer end of the cleaning ring that can be embedded in the annular groove, on the one hand, when the annular elastic airbag is embedded in the annular groove, the possibility of water entering the receiving groove during the water delivery process is reduced, thereby improving the service life of the mechanism; on the other hand, when the annular elastic airbag enters the drain hose with the cleaning ring, it can expand and press against the inner wall surface of the drain hose, thereby improving the cleaning effect of residual clay.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Combine Figure 1 、 Figure 2 and Figure 4 As shown, the drainage hose cleaning mechanism includes a water pipe 1, one end of the water pipe 1 is a hose connection end, and a drainage hose 2 is fixedly connected to the hose connection end; an annular groove 3 is provided on the hose connection end of the water pipe 1 and is located in the drainage hose 2, and a receiving groove 4 is provided on the inner end surface of the annular groove 3; a cleaning ring 7 is provided in the annular groove 3, and a support rod 6 connected to the cleaning ring 7 is provided in the receiving groove 4; an adjustable limit component is provided on the water pipe 1, and when the adjustable limit component is in the limit position , which can prevent the support rod 6 from moving along its own axial direction; a spring 5 is also provided in the receiving groove 4, and the spring 5 is located between the inner end surface of the receiving groove 4 and the inner end of the support rod 6; when the support rod 6 is in the receiving groove 4 and is restricted by the adjustable limiting component, the spring 5 is in a compressed state; when the adjustable limiting component leaves the limiting position, the spring 5 changes from the compressed state to the natural state, and pushes the support rod 6 to move along its own axial direction, and the cleaning ring 7 is driven by the support rod 6 to move from one end of the drain hose 2 toward the other end thereof.

[0022] The drainage hose cleaning mechanism can be applied to various water supply and drainage devices, especially to water supply and drainage devices used in deep foundation pits, to clean the drainage hose 2 after use. When in use, by adjusting the adjustable limit component to leave the limit position, the spring 5 can be changed from a compressed state to a natural state, and the support rod 6 can be pushed to move outward along its own axis, and then the cleaning ring 7 is driven by the support rod 6 to move from one end of the drainage hose 2 toward the other end thereof, so as to clean the residual clay in the drainage hose 2 and dredge the hose wall stuck by the clay.

[0023] The drainage hose 2 is usually a rubber tube. The annular groove 3 is mainly used to place the cleaning ring 7, which is usually coaxial with the water pipe 1. The receiving groove 4 is mainly used to install the spring 5 and the receiving support rod 6. It is usually a circular groove or a square groove opened along the water pipe 1. In order to ensure the cleaning effect, multiple receiving grooves 4 are usually opened on the inner end surface of the annular groove 3 to accommodate multiple springs 5 and support rods 6 to provide sufficient driving force and ensure sufficient structural strength. Preferably, as shown in FIG. Figure 4 As shown, two centrally symmetrical receiving grooves 4 are provided on the inner end surface of the annular groove 3 .

[0024] The spring 5 mainly provides power for the cleaning ring 7 to clean residual clay and unclog the sticky hose wall; the spring 5 is generally made of corrosion-resistant material, preferably stainless steel; and the surface of the spring 5 is usually coated with anti-rust paint; in this way, the spring 5 is not easily corroded during long-term use, thereby increasing the service life of the spring 5.

[0025] The support rod 6 is a part for power transmission and strengthening structural strength, which is usually adapted to the storage groove 4; in order to prevent the support rod 6 from detaching from the storage groove 4, the two ends of the spring 5 are usually fixedly connected to the inner end surface of the storage groove 4 and the inner end of the support rod 6 respectively.

[0026] The cleaning ring 7 is mainly used to clean the residual clay in the drainage hose 2 and to unclog the hose wall stuck by the clay. Generally, the cleaning ring 7 can be made into a structure that is compatible with the annular groove 3, so that when the cleaning ring 7 is retracted into the annular groove 3, the clay stuck on the cleaning ring 7 can be removed.

[0027] The adjustable limit component acts as a switch. When it is in the limit position, it can prevent the support rod 6 from moving along its own axial direction. The adjustable limit component can be of various types, for example: a limit screw threadedly connected to the water pipe 1 and with the limit end extending into the receiving groove 4, a cylinder or oil cylinder provided on the water pipe 1 and with the telescopic end extending into the receiving groove 4, a clamp extending into the receiving groove 4, etc.

[0028] In order to simplify the limiting structure while ensuring the limiting effect, such as Figure 2 As shown, a limiting groove 8 is provided on the support rod 6, and a through hole 9 connected to the receiving groove 4 is provided on the water pipe 1. The adjustable limiting component includes a pin 10 arranged in the through hole 9; when the adjustable limiting component is in the limiting position, the pin 10 is inserted into the limiting groove 8 to limit the support rod 6.

[0029] On the basis of the above, in order to facilitate the adjustment of the latch 10 for limiting, Figure 3 As shown, the adjustable limiting component further includes an elastic button 11 provided on the outer wall of the water pipe 1 , and the pushing end of the elastic button 11 is fixedly connected to the outer end of the latch 10 .

[0030] Preferably, an anti-skid cover with anti-skid patterns is provided on the elastic button 11. By using the anti-skid cover with anti-skid patterns, the possibility of slipping due to sweat, water, etc. on the hands of construction workers when using the elastic button 11 can be reduced.

[0031] Specifically, for example Figure 3 As shown, a button spring 12 is provided between the push end of the elastic button 11 and the outer wall of the water pipe 1. The button spring 12 is in a stretched state. When the support rod 6 is retracted into the receiving groove 4, the elastic force of the button spring 12 automatically inserts the latch 10 into the retaining groove 8, thereby restraining the support rod 6.

[0032] On the basis of the above, in order to reduce the friction of the support rod 6 during the process, Figure 3 As shown, a spherical groove is provided on the inner end of the latch 10, in which a ball 14 is rotatably provided. The provision of the ball 14 can reduce the friction between the latch 10 and the support rod 6, ensuring that the latch 10 and the support rod 6 are not easily damaged.

[0033] Specifically, for example Figure 3 As shown, a limit block 15 is provided on the outer wall of the support rod 6 near the inner end of the support rod 6. The limit block 15 corresponds horizontally to the limit end of the adjustable limit member. By providing the limit block 15 corresponding horizontally to the limit end of the adjustable limit member, the movement limit position of the support rod 6 can be limited to prevent it from being dislodged from the receiving slot 4.

[0034] As a preferred embodiment of the present invention, the drain hose cleaning mechanism is provided with an annular elastic airbag 13 capable of being embedded in the annular groove 3 on the outer end of the cleaning ring 7. The annular elastic airbag 13 is generally made of elastic material, preferably made of rubber.

[0035] When using the above-mentioned drainage hose cleaning mechanism, the construction worker holds the elastic button 11 with his hand and pulls it outward for a distance, so that the pin 10 is separated from the limiting groove 8. Because the elastic force of the spring 5 is greater than the resistance of the annular groove 3 to the annular elastic airbag 13, the annular elastic airbag 13 is separated from the annular groove 3 and moves outward under the action of the elastic force of the spring 5. During the movement, the drainage hose 2 stuck by clay is gradually unfolded by the annular elastic airbag 13 on the cleaning ring 7. At the same time, the clay remaining inside and on the inner wall of the drainage hose 2 is cleaned by the scraping action of the annular elastic airbag 13 and the cleaning ring 7; after the cleaning and dredging is completed, the construction worker pushes the annular elastic airbag 13 inward with his hand, squeezes the spring 5 back through the support rod 6, and then under the elastic force of the button spring 12, the pin 10 is automatically inserted into the limiting groove 8 to restrict the support rod 6, completing the reset.

[0036] The present invention also provides a water supply and drainage device for a deep foundation pit, which includes the above-mentioned drainage hose cleaning mechanism.
