Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in figures 1-5, the invention firstly discloses a variable-capacity tank for environmental sanitation cleaning and sewage suction, which comprises a tank body 1, wherein the tank body 1 comprises a middle cylinder body and end sockets at two sides, a sewage cavity 2 and a clear water cavity 3 which are mutually isolated are arranged in the tank body 1, the clear water cavity 3 is provided with a water inlet 4 for inputting clear water and a water outlet 5 for discharging water for dredging cleaning or road surface cleaning, the sewage cavity 2 is provided with a sewage suction port 6, a sewage discharge port 7 and a negative pressure suction port 8, the sewage suction port 6 and the sewage discharge port 7 are positioned below the negative pressure suction port 8, a suction negative pressure is provided through the negative pressure suction port 8 to suck sewage into the sewage cavity 2 from the sewage suction port 6 below, when the sewage is accumulated to a certain amount and transported to a specified treatment place, the sewage is discharged through the sewage discharge port 7, the sewage cavity 2 and the clear water cavity 3 are mutually isolated through a flexible isolating sheet 9, the flexible isolating sheet 9 is hermetically connected with the inner wall, in fact, the tank body 1 is also divided into the sewage cavity 2 and the clear water cavity 3 by the flexible isolation sheet 9, the flexible isolation sheet 9 is provided with a plurality of bending structures 10 which can extend and expand the sewage cavity 2 and the clear water cavity 3 at two sides, and the bending structures can also be regarded as a fold structure, namely the surface area of the flexible isolation sheet 9 when being unfolded is far larger than the cross-sectional area of the tank body 1. When sewage chamber 2 and clear water chamber 3 all the evacuation, flexible spacing block 9 presents the fold condition of natural sagging, and when sewage chamber 2 and clear water chamber 3 one fill into liquid, the structure of buckling 10 on the flexible spacing block 9 just expands to the opposite side, for traditional elasticity diaphragm (rubber diaphragm) the root receives great pulling deformation when extending to one side, this kind of flexible spacing block 9 with structure of buckling 10 can not pull because of elasticity at the edge basically and produce stress concentration, life is longer.

Specifically, the flexible isolation sheet 9 can be waterproof cloth or a waterproof plastic film or other non-elastic waterproof films, and the waterproof cloth or the waterproof films are connected with the inner wall of the tank body 1 in a sealing manner. Specifically, the number of layers of the single flexible isolating sheet 9 is not limited, for example, the flexible isolating sheet 9 of the embodiment is a water-proof double-layer canvas, which is not only cheap, but also has a longer service life. When actual setting, water proof canvas sets up to extending to the wall that is close to jar body 1 both sides to reduce water proof canvas's edge as far as possible and obtain jar body 1 both sides inner wall's support, avoid receiving the pulling force because of loading water, and then ensure the sealing performance at water proof canvas edge.

In order to detect the sealing performance of the flexible isolation sheet 9 in real time and on line and prevent the sewage in the sewage cavity 2 from permeating or leaking into the clean water cavity 3 or the clean water in the clean water cavity 3 from permeating or leaking into the sewage cavity 2, in this embodiment, the number of the flexible isolation sheets 9 is two, the flexible isolation sheets 9 arranged opposite to each other form an inspection chamber 11 located between the sewage chamber 2 and the clear water chamber 3, the top of the inspection chamber 11 is provided with an access door 12 (the sewage chamber 2 and the clear water chamber 3 can also be provided with the access door 12), and a water discharge check valve 13 is installed at the lower side of the check cavity 11, once leakage occurs, leaked clean water or sewage firstly enters the bottom of the check cavity 11 and flows out from the water discharge check valve 13, thereby indicate the maintainer to overhaul promptly, and during the maintenance, the staff gets into from access door 12, also can irregularly get into through access door 12 and change flexible barrier 9.

In order to realize the sealed installation of the flexible isolation sheet 9, a mounting ring 14 is fixedly connected to the inner wall of the tank body 1 in a sealing welding manner, the edge of the flexible isolation sheet 9 is tightly pressed on the mounting ring 14 through a pressing plate 15 in a sealing manner, the pressing plate 15 is tightly pressed on the mounting ring 14 through a stainless steel bolt 27, and specifically, in the present embodiment, the edge of the flexible isolation sheet 9 is in a shape of a square

The shape wraps the outer surface of the mounting ring 14 (see fig. 5 including the left, right and lower side surfaces of the mounting ring 14, the fastening seal of the flexible isolation sheet 9 on the left side of the mounting ring 14 can enter through the access door 12 from the clean water cavity 3), and the outer surfaces of the flexible isolation sheet 9 and the mounting ring 14 are all compressed through the compression plate 15 to form a tortuous labyrinth seal channel 16, so that the sealing performance of the edge of the flexible isolation sheet 9 is further ensured, meanwhile, the mounting ring 14 is arranged in the middle position in the tank body 1 and can support the inner wall of the tank body 1, further the strength and rigidity of the whole tank body 1 are improved, and the effect of killing two birds with one stone is achieved.

In this embodiment, set up division board 17 in the sewage chamber 2, the edge of division board 17 and the inner wall welding of jar body 1 are sealed, and division board 17 separates sewage chamber 2 for two cavities, and division board 17 forms a vacuum suction chamber 18 with the inner wall of jar body 1, and soil pick-up mouth 6 and negative pressure suction mouth 8 set up on vacuum suction chamber 18, install the control flap 19 that can communicate with sewage chamber 2 on the division board 17, and wherein control flap 19 is automatic control valve, can control through the driver's cabin. Alternatively, the valve may be manually controlled, and a control rod of the valve may extend upward out of the tank 1. Furthermore, when the vacuum suction chamber 18 starts to suck sewage, the control valve 19 is closed, so that the flexible isolation sheet 9 on one side of the sewage chamber 2 is prevented from being pulled to the right side due to negative pressure, and the sealing performance of the edge of the flexible isolation sheet 9 is further protected. Meanwhile, in this embodiment, a filter screen is arranged on the control valve 19, so that sludge or larger particles are isolated in the vacuum suction chamber 18, and the influence on the flexible isolation sheet 9 is avoided, a dirt discharge port 20 is arranged at the bottom of the vacuum suction chamber 18 and used for discharging the sludge or the larger particles in the vacuum suction chamber 18, high-pressure air is input through the vacuum suction chamber 18, and the vacuum suction chamber 18 is also convenient for rapidly discharging the sludge or the larger particles from the dirt discharge port 20.
