Description

Submersible plastic drainage and decontamination joint

Technical Field

The utility model relates to a heavy silt well part, concretely relates to be applied to dive formula plastics drainage of heavy silt well and decontaminate and connect.

Background

The caisson is an important infrastructure in municipal drainage systems. The silt sinking well is generally composed of a well body A1, a rainwater grate A3 at the top of the well body, a drainage pipe A2 arranged on the side wall of the well body and the like (as shown in figure 1). Rainwater flows into the well through the rainwater grate at the top of the well body, and when the water surface in the well gradually rises to the drain pipe on the side wall of the well body, the rainwater flows into a drain pipe network outside the well through the drain pipe.

In the process of rainwater flowing into the silt sinking well, impurities such as sand, leaves and the like around can be brought into the well and gradually deposited at the bottom of the well. Therefore, the sludge and impurities deposited in the well need to be cleaned regularly. If can't in time clear up because of special reason, or because the rainy season rainfall is big, silt siltation speed in the well is accelerated, when leading to silt and debris to accumulate the height that is higher than the drain pipe, silt, debris can get into the drain pipe, will cause the drain pipe to block up when serious.

In order to solve the problem that the drainage pipe is blocked due to excessive sludge and sundries deposited in the silt sinking well, an effective solution is to additionally arrange a drainage and decontamination joint at the opening of the drainage pipe.

As shown in figure 2, the drainage and decontamination joint B is made of cast iron and has an appearance "

The working principle of the drainage pipe blockage prevention of the drainage sewage disposal joint is as follows: when the sludge in the silt sinking well is accumulated to a certain height and reaches the position which is level with the water inlet of the drainage and decontamination joint, the sludge can block the water inlet. Rainwater that flows into the settling well will then accumulate in the settling well and will not flow into the drain through the "drain-clearing joint". Therefore, sundries such as silt mixed in water can continue to form siltation in the silt sinking well, and cannot enter the drain pipe, so that the aim of preventing the drain pipe from being blocked is fulfilled.

When the sediment trap is cleaned. Firstly, cleaning sludge in a silt sinking well; then, a dirt cleaning cover of a drainage dirt cleaning joint is opened by using a tool such as a hook, a water pipe B6 is inserted into the joint, and a small amount of residual sludge and the like in the joint are washed clean; and finally, closing the decontamination cover.

When the water flow is small and the air temperature is low, the phenomena of icing and freezing are easy to occur inside the drainage and decontamination joint and at the position of the drainage pipe opening. In order to not affect the normal drainage of the silt sinking well, the ice melting operation needs to be carried out on the frozen part. At this time, the cleaning cover of the joint needs to be opened first; then, the steam pipe B7 is inserted into the joint and the drain pipe, and the frozen part is melted by high-temperature steam.

The drainage of cast iron material is decontaminated and is connected, can effectually play the problem that prevents the drain pipe jam, but still is in following shortcoming in the use:

(1) the cast iron drainage and decontamination joint is washed and soaked by rainwater and sewage all the year round, so that the cast iron drainage and decontamination joint is easy to generate corrosion; regular maintenance and replacement is required;

(2) the self-weight of the cleaning cover is large, the cleaning cover leans against the well wall after being opened, no fixing measure is provided, and the cleaning cover is easy to fall back and close automatically during the operation of inserting a water pipe or a steam pipe, so that the construction operation is influenced;

(3) the drainage and decontamination joint is formed by assembling a decontamination cover, a joint body and a drain pipe, and the contact surfaces among the drainage and decontamination joint are casting surfaces, so that the sealing effect is poor. When the accumulated water in the well is excessive, the problem of water leakage from the matching surface exists;

(4) the drain pipe is also formed by casting, the dimensional accuracy is not high, and the sealing effect is not good when the drain pipe is connected with an external drain pipe;

(5) when more sludge is deposited in the drainage and decontamination joint or the sludge is completely blocked by ice, the operation of inserting a water pipe or a steam pipe from the top surface is inconvenient, and constructors sometimes need to go down to the bottom of a well for operation;

(6) the cleaning cover of the drainage cleaning joint is designed on the side surface of the finished product, and if the drainage cleaning joint is frozen and blocked, the cleaning cover and the main body are frozen together and cannot be opened;

(7) the drainage and decontamination joint is made of cast iron, the product is heavy, and the construction strength is high during installation and replacement. Overall, the product cost is greater.

Detailed Description

The present invention will be described in further detail with reference to fig. 3 to 11.

As shown in figure 3, the submersible plastic drainage and decontamination joint comprises a main body and a decontamination cover 4.

The main body comprises a diving box 1, a drain pipe 2 and a sewage cleaning pipe 3, wherein the drain pipe 2 is arranged on the side surface of the diving box 1, the sewage cleaning pipe 3 is arranged obliquely above the diving box 1, and the diving box 1, the drain pipe 2 and the sewage cleaning pipe 3 form a similar three-way structure; a plurality of process structural ribs 6 are distributed on the outer wall of the diving box 1; a suspended pin shaft seat 7 is arranged on the outer side surface of the top of the sewage cleaning pipe 3; the suspension type pin shaft seat 7 is provided with a fixed pin shaft hole 9 and a fixed meshing tooth 8.

One end of the dirt removing cover 4 is provided with a matching pin shaft hole 10, the other end of the dirt removing cover is provided with an opening hole 13, and the opening hole 13 is convenient for using a tool to open the dirt removing cover 4; the outer side wall of the matched pin shaft hole 10 is provided with a closed state meshing tooth 11 and an open state meshing tooth 12.

When the main body and the cleaning cover 4 are assembled, bolts are used for penetrating through the pin shaft holes 9 and the matched pin shaft holes 10 and are fastened by nuts so as to achieve the purpose of connection. The cleaning cover 4 can be opened or closed by taking a bolt as a rotating shaft.

When the cleaning cover 4 is in a closed state, the closed state meshing teeth 11 on the cleaning cover 4 and the fixed meshing teeth 8 on the main body are meshed with each other, and in this state, when no external force is applied, the cleaning cover 4 cannot be opened due to the buoyancy of water (as shown in fig. 6); when the cleaning cover 4 is in an open state, the open state engaging teeth 12 on the cleaning cover 4 and the fixed engaging teeth 8 on the main body are engaged with each other, and in this state, the cleaning cover 4 is not closed by its own weight when no external force is applied (as shown in fig. 7).

The main body and the dirt removing cover 4 are both made of engineering plastics and have the characteristics of high strength, corrosion resistance and the like. The whole weight is far lower than that of cast iron products with the same specification and volume.

The utility model discloses a suspension type round pin axle bed 7 hangs in the pipe 3 tops of decontaminating, does not connect completely with the pipe of decontaminating, and this kind of structure has made things convenient for the external other pipe fittings of pipe of decontaminating, has realized the purpose of a structure of dive formula plastics drainage joint, two kinds of using-way.

The gear mesh type fixing structure between the dirt removing cover 4 and the diving box 1 simply and effectively achieves the purposes of fixing the dirt removing cover and preventing toppling.

The technological structural ribs 6 on the outer wall of the diving box 1 effectively enhance the structural strength of the product.

The drainage principle of the submersible plastic drainage and decontamination joint is as follows: when the water level in the desilting well rises to be higher than the bottom of the diving box 1 and reaches a certain height, accumulated water can enter the drainage pipe 2 of the diving type plastic drainage and decontamination joint from the bottom of the diving box 1 and flow into a well drainage pipeline connected with the drainage pipe. The cleaning cover 4 is in a normally closed state, so that leaves and sundries falling from a well mouth are prevented from entering the drainage pipeline through the cleaning pipe 3. Because the bottom opening of the diving box 1 is positioned below the water surface, sundries floating on the water surface can not enter the drain pipe 2 through the bottom opening of the diving box 1, and the blocking probability of a drainage system is greatly reduced. See fig. 8.

The anti-blocking principle of the diving plastic type drainage and decontamination joint is as follows: when the thickness of the sludge deposited in the sludge settling well reaches a certain height and is level with the bottom of the diving box 1, the sludge blocks the bottom opening of the diving box 1, and the accumulated water in the sludge settling well cannot continuously enter the drainage pipe 2 of the submersible plastic drainage and decontamination joint from the bottom of the diving box 1. The accumulated water in the silt settling well can only be accumulated in the well continuously, the silt in the accumulated water is continuously settled, the silt is continuously formed in the range outside the submersible plastic drainage and decontamination joint, and the silt cannot enter the drainage pipeline due to the blockage of the submersible plastic drainage and decontamination joint. See fig. 9.

When the inside of the submersible plastic drainage decontamination joint is washed or melted by steam, firstly, the decontamination cover 4 is opened by a tool and is in an open state; then, a water pipe or a steam pipe extends into the joint from the pipe orifice of the sewage cleaning pipe 3, and corresponding operation is carried out; finally, the water pipe or the steam pipe is withdrawn, and the trash removal cover 4 is closed to be in a closed state. A schematic view of a water or steam pipe extending into the soil cleaning pipe is shown in fig. 10.

The submersible plastic drainage and decontamination joint has the advantages that the decontamination pipe 3 is positioned above the submersible box 1 in an inclined manner, so that when the top of a desilting well is operated, a water pipe or a steam pipe can conveniently extend into the joint through the decontamination pipe; because the sewage disposal pipe 3 and the sewage disposal cover 4 are arranged above the diving box 1 in an inclined manner, the sewage disposal cover can not be soaked by the accumulated water in the well before the diving box is completely submerged by the accumulated water in the well, and the problem that the sewage disposal cover cannot be opened due to freezing can be effectively avoided.

Under certain specific environments, the sewage cleaning pipe 3 of the drainage sewage cleaning joint does not need to cover the sewage cleaning cover 4, but needs to be connected with a pipe fitting with a corresponding caliber and directly communicated to the wellhead of the desilting well. In this case, the pipe fitting and the sewage disposal pipe 3 can be directly connected in an open state of the sewage disposal cover 4 without detaching the sewage disposal cover 4.

The above embodiments are only used for illustrating the present invention, and are not intended to limit the present invention, and those skilled in the relevant art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions also belong to the protection scope of the present invention.

Those not described in detail in this specification are within the skill of the art.
