TECHNICAL FIELD
[0001] The utility model belongs to chemical industry drainage equipment technical field, concretely relates to a kind of automatic control over position alarm for water supply and drainage. BACKGROUND
[0002] Coke oven gas condensate collection pool is mainly used to collect coke oven gas pipeline condensate, and the condensate contains high-concentration volatile phenol, polycyclic aromatic hydrocarbons and heterocyclic compounds such as oxygen, sulfur and nitrogen. It is an industrial organic wastewater with high CODcr, high phenol value and high ammonia nitrogen. The water quality is complex, the pollution concentration is high, and the corrosion is strong. Generally, the anti-corrosion performance of the invasive automatic equipment is poor, the service life is short, and the performance is unstable in corrosive wastewater. After the equipment is damaged, it cannot be found in the inspection gap. Once the water is spilled, it will cause serious environmental accidents.
[0003] At present, the measures taken are to reduce the automatic equipment failure by automatic pumping and low water level operation and increasing the frequency of manual inspection. Due to the reduction of posts, the collection pool is located in the gas area and needs to be inspected by two or more people, the distance between each collection pool is large, the distance between the collection pool and the duty room is far, and the on-site inspection is time-consuming and laborious. Once the inspection is not timely, it is easy to cause environmental accidents, and the on-site gas area pipe network is complex at night, which is easy to cause safety accidents.
[0004] The following situations may occur in the automatic drainage of the collection pool.
[0005] 1. Water pump does not start and spills water environmental accident caused by starting limit failure
[0006] 2. Waste of electric energy and burning of water pump caused by stop limit failure
[0007] 3. Water pump failure does not start and causes water environmental accident
[0008] The above three problems have a great impact on the safety of enterprise production and environmental protection. In order to prevent the above three problems, the inspection frequency needs to be increased. The collection pool is located in the gas area, and the work load and risk coefficient of the post are increased at the same time.
[0009] The existing preventive measures cannot realize real-time fault inspection, and cannot guarantee the safe and stable operation of the condensate collection pool. In order to ensure the normal operation of the collection pool drainage and prevent abnormal problems, the inspection frequency of the post needs to be increased. Due to the continuous reduction of personnel in each unit, it is difficult to ensure the increase of inspection frequency. In addition, abnormal conditions may occur in the inspection gap, which cannot be found and measures cannot be taken in time. Only when the next post personnel inspection can the problem be found. The collection pool is located in the gas area, and there is a relatively large safety hazard on site.
[0010] In order to thoroughly solve the above problems, an automatic water supply and drainage control and over-position automatic alarm device is designed, which sends information to the post duty room in the first time when the water level reaches the set position in abnormal condition, reminding personnel to immediately go to the scene for investigation and treatment to eliminate hidden troubles.

[0017] Preferably, the normally open proximity switch is arranged on the top of the mounting groove, and the normally closed proximity switch is arranged below the normally open proximity switch.
[0018] The three aspects prone to problems of the coal gas collection pool are designed respectively.
[0019] The first design solves the problem of preventing the normally closed proximity switch from failing to start the water pump and causing water overflow. A travel switch is additionally arranged on the upper part of the support frame at the end of the counterweight.

DETAILED DESCRIPTION
[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0030] Example 1, such as Figure 1 As shown, an automatic control over-range alarm for water supply and drainage includes a chassis 1. The chassis 1 has a stable structure and serves as the basic structure, supporting the installation and fixation of other components. A support frame 3 is provided on one side of the top of the chassis 1, and a balance bar 5 is provided on the top of the support frame 3. The support frame 3 is used to raise the balance bar 5. The balance bar 5 is fixed by a connecting pin 4. The connecting pin 4 connects the balance bar 5 and the support frame 3, forming a movable connection structure. The balance bar 5 can rotate around the connecting pin 4.
[0031] A balance bar 5 has a connecting hole 6 at one end and a counterweight 9 at the other. The counterweight 9 increases the stability of the balance bar 5, prevents malfunctions caused by external factors such as water flow, improves anti-interference capabilities, and makes water level monitoring more reliable. A pull rope 7 is installed inside the connecting hole 6, and a float 8 is connected to the end of the pull rope 7. The float 8 floats with changes in water level, driving the movement of the balance bar 5, thus achieving water level measurement through the simple principle of buoyancy. The connecting hole 6 allows the pull rope 7 to pass through, connecting the float 8 and the balance bar 5.
[0032] The support frame 3 is equipped with a high water level trigger switch 14 and a low water level trigger switch 15 on both sides. When the water level reaches the high water level, the support frame 3 contacts the high water level trigger switch 14 to trigger an alarm. When the water level reaches the low water level, the support frame 3 contacts the low water level trigger switch 15 to trigger an alarm. The high water level trigger switch 14 and the low water level trigger switch 15 provide immediate feedback to ensure that the personnel on duty can respond in a timely manner and reduce the risk of environmental accidents.
[0033] The other side of the top of the chassis 1 is provided with a mounting rack 10, which is used to install electrical equipment. The mounting slot 11 is installed on the mounting rack 10, and the normally closed proximity switch 12 and the normally open proximity switch 13 are respectively installed in the mounting slot 11. The mounting slot 11 optimizes the use of space, making the equipment design more compact, and provides convenient installation for small components such as proximity switches. The normally closed proximity switch 12 remains closed when the water level does not reach the set height, which is used for the start control of the water pump, improves the reliability, and avoids misstart caused by poor contact. The normally open proximity switch 13 is turned on when the water level reaches the set height, which is used for the stop control of the water pump, ensures that the water pump stops working when the water level is low, and avoids excessive drainage.
[0034] Now let's talk about the specific design of the above key components:
[0035] The top of the chassis 1 is provided with a plurality of mounting holes 2, and the support frame 3 and the mounting rack 10 are fixed on the top of the chassis 1 through the mounting holes 2. The chassis 1 should be made of corrosion-resistant materials such as stainless steel or corrosion-resistant plastics, which can be used for a long time in harsh environments.
[0036] A plurality of mounting holes 2 are provided on the top of the chassis 1, and these mounting holes 2 are designed as standardized hole positions to facilitate the accurate positioning and installation of the support frame 3 and the mounting rack 10. The diameter and depth of the mounting hole 2 are considered according to the specifications of the bolts used to ensure the firmness of the connection.
[0037] The high water level trigger switch 14 is on the same side as the counterweight 9. When the water level is high, the float ball 8 rises, and the counterweight 9 descends. At this time, the balance rod 5 touches the high water level trigger switch 14. The low water level trigger switch 15 is on the same side as the pull rope 7. When the water level is low, the float ball 8 descends, and at this time, the balance rod 5 touches the low water level trigger switch 15.
[0038] The high water level trigger switch 14 and the low water level trigger switch 15 are respectively connected to the wireless alarm 18 through the high water level wire 16 and the low water level wire 17. The connection of the high water level wire 16 and the low water level wire 17 uses waterproof connectors to improve the protection level and prevent water vapor from entering to cause short circuit.
[0039] The number of mounting slots 11 is 2, which are arranged vertically, and the normally closed proximity switch 12 and the normally open proximity switch 13 are respectively installed through the two mounting slots 11.
[0040] The normally open proximity switch 13 is arranged on the top of the mounting groove 11, and the normally closed proximity switch 12 is arranged below the normally open proximity switch 13. When the water level rises, the float ball 8 is lifted, the counterweight block 9 end of the balance bar 5 is lowered under the action of the counterweight block 9, the balance bar 5 approaches the normally closed proximity switch 12, and the water pump is started. When the water level drops, the float ball 8 is lowered, the counterweight block 9 end of the balance bar 5 is lifted, and the balance bar 5 and the normally open proximity switch 13 are inducted to stop the water pump. When the balance bar 5 cannot be inducted by the normally closed proximity switch 12, the water level continues to rise, the counterweight block 9 end of the balance bar 5 is lowered, and the counterweight block 9 end of the balance bar 5 presses the high water level trigger switch 14 to generate an alarm (the pump failure principle is the same). Conversely, when the water pump does not stop after starting, the float ball 8 end of the balance bar 5 presses the low water level alarm switch to generate an alarm to inform the on-duty personnel.
[0041] According to the selection of the wastewater corrosion, the material of the float ball 8 is selected, the service life of the float ball 8 is prolonged, the original electric detection part is separated from the corrosive wastewater, and the service life of the electrical control equipment is greatly improved. After the high and low water level alarm devices are set, the system can work in the no-inspection mode, and timely alarms are generated when the water level exceeds the set value, so that the water environmental accidents are avoided, the water pump burning problem caused by the normally open proximity switch failure is reduced, and the safety factor of the post operator is improved without inspection at night.
[0042] The standard parts used in the utility model can be purchased from the market, the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the prior art, the mechanical parts and equipment adopt the conventional types in the prior art, the circuit connection adopts the conventional connection mode in the prior art, and the details are not described herein. The contents not described in detail in the description belong to the prior art known by the person skilled in the art.
[0043] The above is only a preferred embodiment of the utility model, and does not limit other forms of the utility model. Any person skilled in the art can change or modify the above disclosed technical content into equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the utility model to the above embodiments still belong to the protection scope of the utility model technical scheme.
