Description

Technical Field

[0001] The invention belongs to the technical field of basement roof drainage, and in particular relates to an automatic basement roof drainage device. Background Art

[0002] Before a complete drainage system is formed during construction operations, precipitation, water accumulation and drainage on the basement roof are mainly carried out by manual sweeping or by setting drainage holes on the basement roof. Manual drainage will consume a lot of time and manpower, and there is no drainage system in the early stage, so it is difficult to drain the accumulated water. Setting drainage holes on the basement roof can easily cause a large amount of accumulated water to flow into the basement. In the early stage, there is no drainage system in the basement, which is prone to serious water accumulation, which is not conducive to the closed operation of the basement. There are not enough pre-buried holes, and the accumulated water in the basement cannot be completely removed. The subsequent opening of the holes is likely to affect the structure of the basement roof. During the construction period, the basement roof is exposed for a long time and is affected by rainy weather for a long time. The accumulated water has a great impact on the on-site appearance and operation. In view of this, we propose an automatic drainage device for the basement roof. Summary of the invention

[0003] The object of the present invention is to provide an automatic drainage device for a basement roof to solve the problems raised in the above-mentioned background technology.

[0004] In view of this, the present invention provides a basement roof drainage automation device, including a drainage pipe, and also including: A water pump, wherein the water pump is fixedly mounted on the drainage pipe, an electric air inlet valve is fixedly mounted on the water outlet end of the water pump, a flow diversion joint is fixedly mounted on one end of the electric air inlet valve, and a pressure gauge is fixedly mounted on the flow diversion joint; A plurality of blocking valves, wherein the blocking valves are respectively fixedly mounted on a plurality of water outlet ends of the diverter joint, and a hose is fixedly mounted on one end of the plurality of blocking valves, a pre-buried pipe is fixedly mounted on the tail end of the hose, a water pipe is fixedly mounted on the top end of the pre-buried pipe, a rubber sleeve is sleeved around the water pipe, a column is fixedly mounted on the top end of the water pipe, a prefabricated plastic mold is sleeved around the column, a top cover is provided above the column, a spring is fixedly mounted between the top cover and the column, a plurality of buckles 2 are fixedly mounted on the top of the column, a buckle 1 connected with the buckle 2 is fixedly mounted on the bottom of the top cover, a plurality of nylon hooks 1 are fixedly mounted on the bottom of the top cover, and a plurality of nylon hooks 2 are fixedly mounted on the top of the column; The automatic controller is arranged on one side of the drainage pipe, and a rain gauge is fixedly installed on the top of the automatic controller.

[0005] In this technical solution, a rain gauge is set up to detect the water content in the roof of the basement. When the water on the roof of the basement reaches an appropriate amount, the automatic controller controls the water pump to start running. The water pump will absorb water from several hoses through the diversion joint, and the hoses will absorb water from the corresponding water pipes through several pre-buried pipes. The water pipes will then absorb water on the column to ensure that all water on the roof of the basement will flow into the column. When it rains, the rain gauge in the overall device can sense the rainfall, and the water pump can automatically precipitate water on the roof of the basement when it rains, reducing the cost and construction period of manual cleaning.

[0006] In the above technical solution, further, the water inlet end of the water pump is fixed to the drain pipe by a plurality of bolts, and the water outlet end of the water pump is fixed to the electric air intake valve by a plurality of bolts.

[0007] In the present technical solution, the structural stability of the water inlet end of the water pump and the drain pipe is ensured, and the structural stability of the water outlet end of the water pump and the electric air inlet valve is ensured. When the electric air inlet valve is opened and operated, the water inlet at the top of the column is in a closed state. Since the hooks on nylon Velcro 1 and nylon Velcro 2 stick to each other and there is suction on the column, it cannot be pushed open by the spring when the water pump is running, thereby ensuring the suction pressure in the column.

[0008] In the above technical solution, further, the pressure gauge is fixed to the diverter joint by a plurality of bolts, and the number of the water outlet ends of the diverter joint is at least 4.

[0009] In this technical solution, the structural stability of the pressure gauge and the diverter joint is ensured, and the diverter joint is ensured to be able to quickly absorb rainwater at multiple locations on the basement roof.

[0010] In the above technical solution, further, the blocking valve is threadedly connected to the water outlet end of the diverter joint, and the hose is threadedly connected to the blocking valve.

[0011] In the present technical solution, it is convenient to separate the blocking valve from the diverter joint and the hose. When the blocking valve is damaged or needs to be repaired or replaced, personnel can quickly remove and install the blocking valve. The diverter joint is provided with multiple joints, and the number of diverter hoses is set according to the suction performance of the water pump. Unnecessary hoses can be closed by the blocking valve.

[0012] In the above technical solution, further, one end of the embedded pipe is threadedly connected to the hose, the top end of the embedded pipe and the water pipe are an integrally formed structure, and the embedded pipe is an L-shaped structure.

[0013] In this technical solution, when the hose is damaged or needs to be replaced, the embedded pipe can be easily removed from the hose to ensure the structural stability of the top of the embedded pipe and the water pipe. The embedded pipe has an L-shaped structure, which is convenient for the column to absorb water and also convenient for the embedded pipe to be embedded.

[0014] In the above technical solution, further, the water pipe is tightly bonded to the rubber sleeve, and the prefabricated plastic mold is fixed to the column by a plurality of screws.

[0015] In this technical solution, the structure of the water pipe and the rubber sleeve is ensured to be stable. The rubber sleeve can protect the water pipe and ensure that the thermal expansion and contraction of external objects in winter will not cause direct damage to the water pipe. The water pipe is first protected by the rubber sleeve.

[0016] In the above technical solution, further, the buckle 1 and the top cover are an integrally formed structure, the buckle 2 and the column are an integrally formed structure, and the buckle 1 and the buckle 2 are both L-shaped structures.

[0017] In the present technical solution, the structural stability of buckle 1 and the top cover is ensured, and the structural stability of buckle 2 and the column is ensured. Buckle 1 and buckle 2 are both L-shaped structures, ensuring that when the top cover is installed on the column, the personnel turns to the top cover and allows the top cover to drive several buckles 1 to rotate until several buckles 1 are buckled with several buckles 2, so that the top cover is stably installed on the column.

[0018] In the above technical solution, further, the bottom end of the spring is tightly welded to the column, and the nylon hook and loop fastener 1 are tightly bonded to the nylon hook and loop fastener 2.

[0019] In this technical solution, the structure of the spring is ensured to be stable. When the negative pressure in the column increases, the column absorbs air and drives the top cover to squeeze the spring and shrink to cover the column. At the same time, nylon Velcro 1 will stick to nylon Velcro 2, ensuring that when there is negative pressure in the column, the top cover will seal the column to prevent other foreign matter from entering the column and affecting the normal operation of the entire device.

[0020] In the above technical solution, further, the plurality of nylon hooks 1 and the plurality of nylon hooks 2 are arranged in a circular shape with equal spacing. In the technical solution, it is ensured that after a plurality of nylon hooks and loops 1 and a plurality of nylon hooks and loops 2 are adhered to each other, the structural stability of the top cover and the column is increased.

[0021] In the above technical solution, further, the automatic controller is electrically connected to the rain gauge, the water pump, the electric air inlet valve blocking valve, and the pressure gauge. In this technical solution, it is ensured that the automatic controller can control the rain gauge, water pump, electric air inlet valve and pressure gauge to work together.

[0022] The beneficial effects of the present invention are: 1. The basement roof drainage automation device is modularized, quickly assembled, and can be used repeatedly. This device feeds back rainfall to the control system through a rain gauge. When the monitoring data value reaches the set threshold, the water pump switch is controlled to establish an automated control system.

[0023] 2. In the automatic drainage device for the basement roof, when the water pump is operating, suction is generated in the pipe. When the water flow at one water inlet is sucked dry, the suction of the water inlet top cover of the column increases, causing the top cover to be closed and stuck by nylon Velcro 1 and nylon Velcro 2.

[0024] 3. For the automatic drainage device for the basement roof, when the water inlet of one or part of the columns is closed, the suction of the water inlets of other columns will increase. At this time, the automatic controller adjusts the air intake of the electric air intake valve according to the pressure feedback from the hose, embedded pipe, water pipe and column pressure gauge.

[0025] 4. For the automatic drainage device on the basement roof, when the electric air inlet valve is opened, the water inlet of the column is in a closed state. Due to the suction of the dragon Velcro 1 and nylon Velcro 2 hooks as well as the hose, embedded pipe, water pipe and column, the top cover cannot be pushed open by the spring when the water pump is running, thereby ensuring the suction pressure in the hose, embedded pipe, water pipe and column.

[0026] 5. The automatic drainage device for the basement roof uses an automated system to drain the basement roof, reducing manual workload and subjective human control. Through the diversion joint at the important node, multi-area pumping can be achieved. Through the column water inlet, pressure measuring valve, and electric air inlet valve, internal suction loss due to air entry can be avoided. In the early stage of pre-embedding, a slope can be set in the pre-embedding area to collect rainwater. The device can be reused, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The structure stability of the top cover 12 and the column 10 is increased by ensuring that the plurality of nylon hooks 121 and the plurality of nylon hooks 122 are adhered to each other.

[0049] Example 10: This example provides an automatic basement roof drainage device, which, in addition to the technical solutions of the above examples, also has the following technical features: the automatic controller 15 is electrically connected to the rain gauge 16, the water pump 2, the electric air intake valve 3, the blocking valve 61, and the pressure gauge 4.

[0050] Among them, it is ensured that the automatic controller 15 can control the rain gauge 16, the water pump 2, the electric air inlet valve 3 and the pressure gauge 4 to work together.

[0051] Working principle: When there is water on the roof of the basement or in rainy weather, the rain gauge 16 can automatically detect the water content in the roof of the basement. When the water content on the roof of the basement reaches the threshold set by the rain gauge 16, the rain gauge 16 will feed back the sensed information to the automatic controller 15. Then, the automatic controller 15 will control the water pump 2, the electric air inlet valve 3, the blocking valve 61 and the pressure gauge 4 to start operation. The water pump 2 will absorb water from several hoses 7 through the diverter joint 6. At the same time, the pressure gauge 4 will detect the water content in each hose 7. At the same time, the hose 7 will absorb water from the corresponding water pipe 9 through several pre-buried pipes 8. The water pipe 9 will then absorb water from the column 10 to ensure that all water on the roof of the basement will flow into the column 10. When it rains, the rain gauge 16 in the overall device can sense the rainfall, and the water pump 2 can automatically precipitate water on the roof of the basement when it rains, reducing the cost and construction period of manual cleaning. When the pressure gauge 4 detects that the water content in one of the hoses 7 is too little, the spring 14 supports the top cover 12, and the suction force in the column 10 is insufficient to close the top cover 12. When the water pump 2 is running and there is no water flowing at the water inlet of the column 10, the suction force in the column 10 increases to absorb air, which will drive the top cover 12 to squeeze the spring 14 and shrink to cover the column 10. The suction force in the hose 7, the embedded pipe 8, the water pipe 9 and the column 10 increases, causing the top cover 12 to close. The top cover 12 will seal the column 10 to prevent other foreign matter from entering the column 10 and affecting the normal operation of the entire device.

[0052] When the top cover 12 is closed, the suction force in the hose 7, the embedded pipe 8, the water pipe 9, and the column 10 increases, and the value change of the pressure gauge 4 reaches the threshold value, and the electric air intake valve 3 automatically starts to operate, and by controlling the entry of air, the suction force of the hose 7, the embedded pipe 8, the water pipe 9, and the column 10 is weakened, preventing the increase of suction force from causing the remaining cover 12 to close. When the suction force is weakened, the water inlet of the column 10 is closed, because the nylon hook and loop 1 121 on the top cover 12 and the column 10 will stick to the nylon hook and loop 2 122, so that the spring 14 cannot overcome the combined force of the suction force and the hook and loop, and the normal water pumping of the remaining hoses 7, the embedded pipe 8, the water pipe 9, and the column 10 is guaranteed. When the water pump 2 is turned off, the internal and external pressure difference of the hose 7, the embedded pipe 8, the water pipe 9 and the column 10 decreases, the internal suction force of the hose 7, the embedded pipe 8, the water pipe 9 and the column 10 weakens, the nylon Velcro suction force is much smaller than the elastic force of the spring 14, and the water inlet top cover 12 of the column 10 enters the open state.

[0053] The automatic controller 15 is used to connect the rain gauge 16, the water pump 2, the electric air intake valve 3 and the pressure gauge 4, and can be used to adjust the threshold of the rain gauge 16, the air intake volume of the electric air intake valve 3, and the switch state of the system. It is the "brain" of the whole system. Figure 2 shown.

[0054] When the rain gauge 16 reaches the set threshold, it sends information to the automatic controller 15. The automatic controller 15 receives the signal and controls the switch of the water pump 2. When the value of the pressure gauge 4 changes, the air intake of the electric air intake valve 3 is adjusted to maintain the suction balance. After all the air intake valves are closed, the water pump 2 stops and restarts within a certain period of time to detect whether the water flow is drained.

[0055] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
