Description

Technical Field

[0001] The present invention relates to the technical field of underwater operations, and particularly to a repair device for the pool wall of an underground water purification plant with an isolation function. Background Art

[0002] The pool walls of underground water purification plants are in an environment of water erosion for a long time, and problems such as damage and cracks are likely to occur. Traditional pool wall repair methods often require the pool to be emptied before the operation can be carried out, which not only consumes a large amount of time but also affects the normal operation of the water purification plant. When repairing the pool wall under water, many challenges are faced, such as extremely poor visibility due to the turbidity of the water in the pool and complex water body components. These factors exacerbate the difficulties in accurately discriminating the damage of the pool wall and isolating the repair area.

[0003] The Chinese patent application with the publication number CN119163088A, an underwater repair isolation device for the pool wall of an underground water purification plant and its water-retaining repair construction method, although discloses the water-retaining repair operation for the pool wall of the water purification plant, still cannot overcome the problems of extremely poor visibility due to the turbidity of the water in the pool and complex water body components. Summary of the Invention

[0004] In order to overcome the disadvantages of facing challenges such as extremely poor visibility due to the turbidity of the water in the pool and complex water body components when repairing the pool wall under water, the present invention provides a repair device for the pool wall of an underground water purification plant with an isolation function.

[0005] The technical implementation scheme of the present invention is as follows: A repair device for the pool wall of an underground water purification plant with an isolation function includes a housing, an isolation plate, a first active push rod, and a vacuum pumping housing; The isolation plate is fixedly connected to the rear side inside the housing and is arranged in a U shape; The middle of the isolation plate has a telescopic plate, and a first active push rod is fixedly connected to the isolation plate, and the telescopic plate is driven by the first active push rod to stretch and contract; A vacuum pumping housing is installed on the front side of the isolation plate, and the vacuum pumping housing contacts the pool wall and pumps out the air through it; It also includes an air intake and exhaust pipe, a water inlet pipe, and a sewage discharge pipe; The upper side of the vacuum pumping housing is communicated with the air intake and exhaust pipe; The upper side of the vacuum pumping housing is communicated with the water inlet pipe; A sewage discharge pipe is installed on the lower side of the vacuum pumping housing.

[0006] Furthermore, the bottom of the sewage discharge pipe is 1 cm away from the inner bottom of the vacuum pumping housing.

[0007] Furthermore, it also includes an inflatable airbag, and an inflatable airbag is arranged on the front side of the vacuum pumping housing.

[0008] Furthermore, it also includes a standing plate, and the standing plate is fixedly connected to the rear side inside the housing.

[0009] Furthermore, it also includes an identification camera, and the identification camera is installed on the top of the housing.

[0010] Further, it further includes a liquid drainage component. The liquid drainage component is installed at the bottom of the cover housing, and the water inside the cover housing is drained to the outside of the cover housing through the liquid drainage component.

[0011] Further, it further includes a first vertical plate, a second vertical plate, a baffle plate, a collection component, a motor, and a filter plate. The right front side of the cover housing is fixedly connected with the first vertical plate and the second vertical plate which are distributed in parallel, and the second vertical plate is located at the right rear of the first vertical plate. The front side of the first vertical plate is fixedly connected with a baffle plate. A collection component is arranged between the first vertical plate and the second vertical plate, and the adhesion is collected through the collection component. The upper part of the right front side of the cover housing is provided with a motor. At least 6 filter plates are installed on the long rotating shaft of the motor.

[0012] Further, the contact side of the baffle plate with the pool wall is made of rubber material.

[0013] Further, the collection component is a filter screen, and the filter screen slides between the first vertical plate and the second vertical plate. It further includes a second active push rod, a connection block, a water pipe, an isolation shell, and a nozzle. A plurality of second active push rods are installed on the right side plate of the cover housing. The telescopic part of the second active push rod is fixedly connected with a connection block. A water pipe is fixedly connected to the upper side of the connection block, and a pump is arranged on the water pipe to pump and suck water. The left side of the water pipe is fixedly connected with an isolation shell, and the isolation shell covers the left side of the filter screen and is fixedly connected with it. The right side of the water pipe is fixedly connected with a nozzle, and the nozzle faces the filter plate.

[0014] Further, it further includes a waterproof film. A waterproof film is connected between the cover housing and the water pipe. When the water pipe moves left and right, the water in the purification pool is prevented from entering the cover housing through the waterproof film.

[0015] The present invention has the following advantages: In the present invention, by the close contact between the cover housing and the pool wall, the water flow from the purification pool into the cover housing can be significantly reduced. Cooperating with the liquid drainage component at the bottom, the infiltrated water can be discharged in time, so that a low water depth state of 1-2 cm is maintained inside the cover housing. In this way, it not only ensures the stable operation of the device under the condition of water, but also creates clear observation conditions for the recognition camera to observe the pool wall.

[0016] In the present invention, by driving the U-shaped isolation plate by the first active push rod, the vacuum pumping housing is closely attached to the pool wall. Through the vacuum pumping operation, a completely water-impermeable working space is formed between the inner rear wall of the cover housing, the U-shaped isolation plate and the pool wall, which greatly guarantees the safety and continuity of the repair operation.

[0017] In view of the problem that sundries are easily attached to the vacuum pumping housing during operation with water, before vacuum pumping, a large amount of water is first injected into the vacuum pumping housing through the water inlet pipe to wash away the sundries inside the vacuum pumping housing and the sundries between the inflatable airbag and the pool wall, and the sewage is discharged in time through the sewage pipe and the liquid discharge assembly. Subsequently, air is sent in through the air inlet and extraction pipe to blow away the remaining moisture, and then the inflatable airbag is inflated to closely contact the pool wall, ensuring that the vacuum pumping housing is clean and fully fits the pool wall, so as to achieve a stable and reliable vacuum adsorption effect.

[0018] The motor of the present invention drives at least 6 detachable filter plates to rotate, and can scrape the adhesions on the pool wall over a long distance. When adhesions accumulate on the right side of a filter plate, the motor drives the filter plate to rotate clockwise, replaces the new filter plate to continue the operation, and ensures the comprehensiveness and high efficiency of cleaning the adhesions on the pool wall.

[0019] When the filter plate scrapes the adhesions, the pump on the water pipe works, and the water sprayed by the nozzle forms a water flow to the left. This water flow can stably intercept the scraped adhesions on the right side of the filter plate, prevent them from floating in the purification pool, and at the same time can self-clean the filter plate on the left side of the motor and wash the adhesions towards the filter screen for collection, effectively maintaining the water quality cleanliness of the purification pool.

[0020] After the pool wall repair work of the present invention is completed, in the cleaning pool, under the second active push rod, the filter screen enters the rotation range of the filter plate. The motor drives the filter plate to rotate, and can transfer the adhesions collected by the filter screen, and at the same time cooperate with flushing water from top to bottom, and can quickly wash the adhesions clean.

Detailed implementation manners

[0023] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] Embodiment 1: An underground water purification plant pool wall repair device with an isolation function, as Figures 1-3 、 Figure 9 shown, includes a housing 1, a partition board 2, a first active push rod 3 and a vacuum extraction housing 4; openings are provided on the upper side and the front side of the housing 1; a U-shaped partition board 2 is fixedly connected to the rear inner side of the housing 1; a telescopic board 2a is provided in the middle of the partition board 2, a first active push rod 3 is fixedly connected to the partition board 2, and the telescopic part and the fixed part of the first active push rod 3 are respectively fixedly connected to both sides of the telescopic board 2a, and the telescopic board 2a is driven to stretch and contract by the first active push rod 3; a vacuum extraction housing 4 is installed on the front side of the partition board 2, and the vacuum extraction housing 4 is in contact with the pool wall and evacuated, so that a non-seeping space for workers to work can be formed between the rear inner wall of the housing 1, the U-shaped partition board 2 and the pool wall; It further includes an intake and extraction air pipe 5, a water inlet pipe 6 and a sewage pipe 7; the upper side of the vacuum extraction housing 4 is communicated with the intake and extraction air pipe 5, and air is sent into and extracted from the vacuum extraction housing 4 through the intake and extraction air pipe 5; the upper side of the vacuum extraction housing 4 is communicated with the water inlet pipe 6, and water is pumped into the vacuum extraction housing 4 through the water inlet pipe 6; a sewage pipe 7 is installed on the lower side of the vacuum extraction housing 4.

[0025] The bottom of the sewage pipe 7 is 1 cm away from the inner bottom of the vacuum extraction housing 4, so that the sewage pipe 7 can better pump out the liquid and sundries in the vacuum extraction housing 4.

[0026] It further includes an inflatable airbag 4a, and an inflatable airbag 4a is provided on the front side of the vacuum extraction housing 4.

[0027] It further includes a standing board 8, and a standing board 8 is fixedly connected to the rear inner side of the housing 1.

[0028] It further includes an identification camera 9, and an identification camera 9 is installed on the top of the housing 1.

[0029] It further includes a liquid drainage assembly 10. The liquid drainage assembly 10 is installed at the bottom of the housing 1, and the water in the housing 1 is drained outside the housing 1 through the liquid drainage assembly 10.

[0030] When the present invention works, first, the present invention is transferred into the purification pond by a hoisting device or a mobile device, and the hoisting device or the mobile device drives the present invention to move subsequently. First, make the front opening of the housing 1 face the pool wall, cover the housing 1 on the pool wall, as Figure 9 shown in the state. Then, control the hoisting device or the mobile device to drive the present invention to move along the pool wall. Since the housing 1 is in contact with the pool wall, the housing 1 always covers the pool wall, thereby reducing the water in the purification pond from flowing into the housing 1. This enables the present invention to work with water, and part of the water that seeps into the housing 1 can be sucked out of the housing 1 through the liquid drainage assembly 10. In this way, the state of less water in the housing 1 is ensured. For example, the water depth in the housing 1 is maintained at 1 cm - 2 cm. This facilitates the identification camera 9 to observe the pool wall during the movement of the present invention.

[0031] Furthermore, when the identification camera 9 discovers that the pool wall needs to be repaired, as Figure 1 shown, the hoisting device or the mobile device stops driving the present invention to move. Then, control the telescopic part of the first active push rod 3 to push out, stretch the telescopic plate 2a, cover the vacuum extraction housing 4 on the pool wall, and then control the air intake and extraction pipe 5 to evacuate the air in the vacuum extraction housing 4, so that the vacuum extraction housing 4 is adsorbed on the pool wall, enabling the rear wall inside the housing 1 and the U-shaped isolation plate 2 to form a water-tight space for workers to work with the pool wall. Workers can enter the present invention from the upper opening and stand on the standing plate 8 to repair the broken pool wall. In this way, the present invention forms a water-tight space for workers to work with the rear wall inside the housing 1 and the U-shaped isolation plate 2 and the pool wall, avoiding a large amount of water seepage during the repair process that may occur when only relying on the housing 1 without making a sealing treatment, which affects the repair work of workers.

[0032] It should be noted that since the present invention works with water, there will be some sundries on the vacuum extraction housing 4, and the impurities will affect the vacuum extraction effect of the vacuum extraction housing 4 or cause blockage of the air intake and extraction pipe 5 (or air pump). Specifically, because there will be adhesives on the pool wall, although the adhesives can be scraped off through structures such as scrapers, there will still be sundries remaining on the pool wall. After the vacuum extraction housing 4 comes into contact with the pool wall, these sundries will adhere to the vacuum extraction housing 4.

[0033] Therefore, before evacuating the vacuum of the vacuum evacuation housing 4, after the vacuum evacuation housing 4 is placed over the pool wall, first control the water inlet pipe 6 to send a large amount of water into the vacuum evacuation housing 4, and wash away the sundries inside the vacuum evacuation housing 4 through the water. At this time, control the inflatable airbag 4a to deflate to a flat state, so that there is a gap between the inflatable airbag 4a and the pool wall. Then, the water sent into the vacuum evacuation housing 4 by the water inlet pipe 6 can seep out from the gap between the inflatable airbag 4a and the pool wall, washing away the sundries between the inflatable airbag 4a and the pool wall. The generated sewage is discharged through the sewage pipe 7 and the liquid discharge assembly 10. After that, control the air inlet and extraction pipe 5 to send air into the vacuum evacuation housing 4, use the air to blow away the water inside the vacuum evacuation housing 4 and the water between the inflatable airbag 4a and the pool wall. Then control the inflatable airbag 4a to inflate and expand, so that the inflatable airbag 4a is in full contact with the pool wall. Then control the air inlet and extraction pipe 5 to extract air, realizing the vacuum evacuation work of the vacuum evacuation housing 4 on the pool wall. In this way, the present invention can ensure the cleanliness of the vacuum evacuation housing 4 during water-carrying operation, and at the same time ensure the full contact between the inflatable airbag 4a and the pool wall, so as to achieve a stable vacuum adsorption effect on the pool wall, enabling workers to safely repair the pool wall within the present invention.

[0034] Embodiment 2: On the basis of Embodiment 1, as Figures 1-9 shown, it further includes a first vertical plate 101, a second vertical plate 102, a baffle 103, a collection assembly, a motor 105 and a filter plate 106; the right front side of the housing 1 is fixedly connected with the first vertical plate 101 and the second vertical plate 102 which are arranged in parallel, and the second vertical plate 102 is located at the right rear of the first vertical plate 101; the front side of the first vertical plate 101 is fixedly connected with the baffle 103, and a large amount of water is isolated outside the housing 1 through the baffle 103; a collection assembly is arranged between the first vertical plate 101 and the second vertical plate 102, and the adhesives are collected through the collection assembly; the upper part of the right front side of the housing 1 is provided with the motor 105; at least 6 filter plates 106 are installed on the long rotating shaft of the motor 105, and the filter plates 106 are detachably connected.

[0035] Among them, the contact side of the baffle 103 with the pool wall is made of rubber material; the filter plates 106 are annularly and equidistantly distributed, and the two filter plates 106 located on the front and rear sides can block the opening on the right front side of the housing 1.

[0036] The collection component is the filter screen 104, and the filter screen 104 slides between the first vertical plate 101 and the second vertical plate 102; it also includes a second active push rod 201, a connecting block 202, a water pipe 203, an isolation shell 204, and a nozzle 205; a plurality of second active push rods 201 are installed on the right side plate of the housing 1; the telescopic part of the second active push rod 201 is fixedly connected to the connecting block 202; the connecting block 202 is fixedly connected to the water pipe 203 on the upper side, and a pump 203a is provided on the water pipe 203 to pump and suck water; the left side of the water pipe 203 is fixedly connected to the isolation shell 204, and the isolation shell 204 covers and is fixedly connected to the left side of the filter screen 104; the right side of the water pipe 203 is fixedly connected to the nozzle 205, the nozzle 205 faces the filter plate 106, and the left side of the nozzle 205 is arc-shaped.

[0037] It also includes a waterproof film 206. A waterproof film 206 is connected between the housing 1 and the water pipe 203. When the water pipe 203 moves left and right, the waterproof film 206 prevents the water in the water purification tank from entering the housing 1.

[0038] Considering that after the water purification tank is used for a long time, there will be adhesives on its pool wall. If not cleaned, it will affect the vacuum pumping work of the vacuum pumping housing 4 and the repair work of the pool wall. Based on this, the present invention proposes the following solutions: Such as Figure 1 、 Figure 4 、 Figure 5 As shown in

[0039] Further, while the filter plate 106 scrapes the adhesion on the pool wall, the pump 203a is controlled to operate, so that the water in the water pipe 203 is sent out from the nozzle 205 and inhaled from the isolation shell 204; for the filter plate 106, there is a water flow to the left, so that the adhesion scraped from the pool wall can continuously stay on the right side of the filter plate 106 instead of floating in the purification pool; further, the water flow to the left can also wash away the adhesion on the filter plate 106 on the left side of the motor 105 and move it towards the filter screen 104; further, the water flow to the left can also wash the adhesion between the first vertical plate 101 and the second vertical plate 102 towards the filter screen 104 for collection, avoiding the adhesion from floating, and at the same time avoiding the adhesion from being carried out into the purification pool when the filter plate 106 rotates clockwise. In this way, the present invention can perform a long-distance scraping operation on the adhesion on the pool wall through the rotation of multiple filter plates 106, and at the same time, the water flow to the left, on the one hand, can make the scraped adhesion stay on the right side of the filter plate 106, avoiding the adhesion from floating in the purification pool after scraping, on the other hand, can realize the self-cleaning work of the adhesion on the filter plate 106 on the left side of the motor 105, and on the other hand, can also realize washing the adhesion on the filter screen 104 for collection.

[0040] Further, after the repair work on the pool wall is completed, when the present invention is transferred to the cleaning pool for cleaning, the telescopic part of the second active push rod 201 can be controlled to push the connecting block 202, the water pipe 203, the isolation shell 204, and the nozzle 205 to move to the right, so that it changes from Figure 5 to Figure 6 During the transformation, the filter screen 104 moves to the right under the drive of the isolation shell 204, so that the arc-shaped filter screen 104 is within the rotation range of the filter plate 106, and then the motor 105 is controlled to drive the filter plate 106 to rotate, and the adhesion collected by the filter screen 104 is scraped and transferred out by the filter plate 106. At the same time, flushing water from top to bottom can quickly wash away the adhesion; at the same time Figure 6 When in the state, the rotation of the filter screen 104 can scrape the adhesion at the nozzle of the nozzle 205, so that the self-cleaning work of the present invention can be realized.

[0041] It should be noted that the first active push rod 3 and the second active push rod 201 can be pneumatic push rods, and the liquid discharge assembly 10 can be a water pump.
