Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection detection, and relates to an installation structure of a detection sampling device in a wastewater treatment system. Background Art

[0002] Industrial wastewater refers to wastewater, sewage and waste liquid generated during industrial production, which contains industrial production materials, intermediates and products lost with water, as well as sewage generated during the production process. With the rapid development of industry, the types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly widespread and serious, threatening human health and safety.

[0003] Therefore, the state requires enterprises to treat wastewater before discharging it, reduce the total amount of pollutants in the wastewater, make it meet the discharge standards or environmental capacity requirements, and finally discharge the treated clean water into water bodies or urban pipes. Although people have treated wastewater, there are still problems such as incomplete wastewater treatment and excessive discharge. Therefore, environmental protection departments often monitor the water quality of wastewater that has been discharged or is being treated.

[0004] Water quality monitoring is an important part of environmental protection departments' environmental monitoring, and is also an important activity carried out by wastewater treatment environmental protection companies. In order to achieve the purpose of continuous monitoring of wastewater quality, in the prior art, monitoring departments generally design online continuous monitoring systems in wastewater drainage systems. In wastewater monitoring systems, the link of wastewater detection sampling is very important, and it is an important factor in determining whether the detection results are accurate. Specifically, the sampling operation is generally performed by placing a submersible pump into a wastewater collection tank. For example, Chinese patent [Application No.: 201220085253.X] discloses an integrated pump station with a deodorization device, including an integrated cabin, the integrated cabin includes a liquid storage tank, a maintenance cabin, a deodorization device cabin, a gas mixing cabin, a reaction cabin, and a fan cabin; a liquid inlet is provided on the side wall of the liquid storage tank, a submersible pump is installed in the liquid storage tank; a liquid outlet pipe is installed in the maintenance cabin; one end of the liquid outlet pipe extends into the liquid storage tank and communicates with the submersible pump, and the other end of the liquid outlet pipe passes through the maintenance cabin. The submersible pump is fixed at the bottom of the liquid storage tank, and a ladder is designed on the bulkhead of the liquid storage tank to enable installation personnel to install or repair the submersible pump.

[0005] However, under actual working conditions, the water flow in the wastewater pool is relatively turbulent. The submersible pump is installed in the above manner. Although the installation and positioning are stable, since the submersible pump is generally deep in the water, the above installation method makes the installation and operation of the submersible pump very difficult; at the same time, when the submersible pump needs to be taken out for maintenance, it needs to be manually picked up and dragged out, which makes the maintenance of the submersible pump very inconvenient. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose an installation structure for a detection and sampling device in a wastewater treatment system. The technical problem solved by the present invention is how to ensure that the submersible pump can be stably installed and positioned while making the installation and maintenance of the submersible pump more convenient.

[0007] The object of the present invention can be achieved through the following technical solutions: an installation structure of a detection sampling device in a wastewater treatment system, the wastewater treatment system includes a wastewater collection tank and a working wellhead communicated with the wastewater collection tank, the detection sampling device includes a submersible pump located in the wastewater collection tank and a water outlet pipe connected to the water outlet of the submersible pump, the water outlet pipe extends from the wastewater collection tank to the working wellhead, characterized in that the installation structure includes a fixing rod inserted into the bottom of the wastewater collection tank in a vertical direction and fixed at the bottom of the wastewater collection tank and a fixing frame fixed above the working wellhead, a clamp is fixed on the submersible pump, the clamp has an annular clamping ring portion, the clamping ring portion is sleeved on the fixing rod and is gap-matched with the fixing rod, a winch is fixed to the fixing frame, the steel cable of the winch extends from the working wellhead into the wastewater collection tank and is fixedly connected to the submersible pump and straightened, and the clamping ring portion can slide along the fixing rod under the pulling of the steel cable.

[0008] Different from the prior art, in the installation structure of the detection and sampling device, by designing a fixing rod and a winch and by the cooperation between the two and the submersible pump, it is ensured that the submersible pump can be stably installed and positioned, while making the installation and maintenance of the submersible pump more convenient; specifically, on the one hand, by inserting the fixing rod into the bottom of the wastewater collection tank, the ring part of the clamp fixed on the submersible pump is sleeved on the fixing rod and cooperates with the gap of the fixing rod, that is, in this way, the submersible pump and the fixing rod are slidingly connected, and the submersible pump can be positioned with the fixing rod in the radial direction; when the submersible pump is lowered and placed under the water surface of the wastewater collection tank under the action of the winch, the above-mentioned cooperation with the fixing rod enables the submersible pump to be reliably positioned in a turbulent water environment, thereby realizing the stable installation and positioning of the submersible pump; and at this time, in cooperation with the steel cable on the winch, that is, at this time, the steel cable is stretched straight to pull the submersible pump, which can provide further auxiliary positioning for the installation of the submersible pump, thereby further improving the installation and positioning of the submersible pump. Stability; on the other hand, the installation or maintenance of the submersible pump is controlled by the winch. When installation is required, it is only necessary to make the clamp on the submersible pump match the gap with the fixed rod outside the working wellhead in advance, then install the outlet pipe, and then fix the steel cable, and then control the winch to lower until the submersible pump slides below the water surface along the fixed rod to complete the installation; when maintenance is required, it is only necessary to control the winch to pull the submersible pump up to take out the submersible pump for maintenance operations; that is to say, the entire installation and maintenance process does not require manual installation or removal in the wastewater collection tank, thereby greatly improving the convenience of installation and maintenance of the submersible pump; at the same time, the above-mentioned fixed rod not only provides a stable positioning foundation for the submersible pump, but also can provide guidance for the lifting and lowering of the submersible pump, so that the lifting and lowering operations during the installation and maintenance of the submersible pump are smoother, which can further improve the convenience of installation and maintenance of the submersible pump; in addition, in this installation structure, the ladder structure is cancelled, which can simplify the structure and help reduce the construction cost of the entire wastewater treatment system.

[0009] In the installation structure of the detection sampling device in the above-mentioned wastewater treatment system, the lower end of the fixing rod has a conical insertion end. In the wastewater treatment system, there will be a thick mud layer at the bottom of the wastewater collection pool. Through the design of the above insertion end, the fixing rod can be inserted deeper into the bottom of the wastewater collection pool, so that the fixing rod can be firmly fixed, and then the fixing rod can provide a stable positioning foundation for the installation of the submersible pump, ensuring that the submersible pump can be firmly installed and positioned.

[0010] In the installation structure of the detection sampling device in the above-mentioned wastewater treatment system, an installation box is fixed on the fixed frame, a positioning sleeve 1 is fixed on the installation box, a horizontal bar is fixed at the working well mouth, a positioning sleeve 2 located on the same axis as the positioning sleeve 1 is fixed on the horizontal bar, and the fixing rod passes through the positioning sleeve 1 and the positioning sleeve 2 in sequence and is fixed to the two by bolts respectively. Through the design of the above positioning sleeve 1 and the positioning sleeve 2, combined with the fixing point at the insertion end of the fixing rod, the fixing rod is fixed by three fixing points, which greatly improves the stability of the fixing rod itself, so that the fixing rod can provide more reliable positioning for the submersible pump, which is conducive to improving the stability of the installation and positioning of the submersible pump.

[0011] In the installation structure of the detection sampling device in the wastewater treatment system, the upper end of the fixing rod is threadedly connected to a limiting head, the limiting head is located above the positioning sleeve 1, and the limiting head has a spherical limiting portion, the diameter of which is larger than the outer diameter of the positioning sleeve 1. The above limiting head design can prevent the fixing rod from sinking due to the soft mud layer at the bottom of the pool, and ensure that the fixing rod can always provide a reliable positioning foundation for the submersible pump, thereby facilitating the stability of the installation and positioning of the submersible pump.

[0012] In the installation structure of the detection sampling device in the wastewater treatment system, the fixing rod is divided into several short rods, and two adjacent short rods are threadedly connected. Through the above segmented design of the fixing rod, the length of the fixing rod can be flexibly adjusted according to the installation requirements, which is conducive to improving the convenience of submersible pump installation.

[0013] Preferably, in the installation structure of the detection sampling device in the wastewater treatment system, the fixing rod is a square tube, and the clamp is sleeved on the fixing rod and forms a circumferential positioning with the fixing rod. Through the above design, the stability of the installation and positioning of the submersible pump can be further improved.

[0014] In the installation structure of the detection sampling device in the above-mentioned wastewater treatment system, the winch is fixed on the installation box, and a limit opening is formed between the casing of the winch and the inner wall of the installation box, which is opposite to the straight pipe section of the water outlet pipe, and the straight pipe section of the water outlet pipe can extend along the limit opening. In the prior art, a water outlet pipe generally includes a straight pipe section and a curved pipe section; when a submersible pump needs to be installed, after the straight pipe section of the water outlet pipe is installed, since the straight pipe section of the water outlet pipe is located in the limit opening at this time, when the straight pipe section descends with the submersible pump, the straight pipe section is restricted by the limit opening and will not bend excessively and interfere with surrounding components, thereby allowing the installation operation of the submersible pump to proceed smoothly, thereby facilitating the improvement of the convenience of submersible pump installation; when the submersible pump needs to be repaired, the curved pipe section of the water outlet pipe needs to be removed first, and then the submersible pump is controlled to rise. At this time, the water outlet pipe will rise with the rise of the submersible pump. Then, through the design of the above limit opening, the straight pipe section is restricted by the limit opening and will not bend excessively and interfere with surrounding components, thereby allowing the maintenance operation of the submersible pump to proceed smoothly, thereby facilitating the improvement of the convenience of submersible pump maintenance.

[0015] In the installation structure of the detection sampling device in the above-mentioned wastewater treatment system, the clamp includes a strip-shaped connector, one side of the connector has a ring-shaped fixed ring portion, the pump body of the submersible pump is inserted into the fixed ring portion and fixedly connected to the fixed ring portion, the clamp portion is located on the other side of the connector, the clamp portion includes a band-shaped ring body, one end of the ring body has a locking seat, the other end of the ring body is inserted into the locking seat and the outer side surface of the ring body close to the other end has a rack portion, a locking screw with an elliptical cross-section is inserted into the locking seat, and the external thread of the locking screw is meshed with the above-mentioned rack portion. Through the design of the elliptical locking screw and the rack portion in the above-mentioned clamp portion, the clamp portion is not easy to loosen when it is sleeved on the fixed rod and matched with it, so that the stability of the installation and positioning of the submersible pump can be ensured.

[0016] In the installation structure of the detection sampling device in the wastewater treatment system, a cover plate is fixed at the working well mouth, a limiting groove is provided on the cover plate, one end of the limiting groove is connected to the outside, the width of the limiting groove is the same as the diameter of the steel cable, and the steel cable passes through the limiting groove and contacts and abuts against the groove walls on both sides of the limiting groove. Through the design of the limiting groove, the steel cable is limited, so that the positioning of the steel cable is more stable when it is straightened to pull the submersible pump.

[0017] In the installation structure of the detection sampling device in the wastewater treatment system, a positioning hole is also provided on the cover plate, and the water outlet pipe is inserted into the positioning hole and forms a circumferential positioning with the positioning hole. Through the above design, the water outlet pipe can also be effectively positioned, so that the submersible pump can be installed and positioned more stably through the coordinated positioning of the fixing rod, the steel cable and the water outlet pipe.

[0018] Compared with the prior art, the installation structure of the detection and sampling device in the wastewater treatment system has the following advantages: the installation structure is positioned in coordination with the submersible pump through the fixing rod, the steel cable and the outlet pipe, thereby ensuring that the submersible pump can be stably installed and positioned in a turbulent water surface environment; at the same time, through the action of the winch and the fixing rod, the installation and maintenance of the submersible pump does not require going down the well, making the installation and maintenance of the submersible pump more convenient.
