Description

Technical Field

[0001] This utility model relates to the field of coal mine safety monitoring technology, and in particular to a lever-type automatic water discharge device for a bundled tube monitoring pump station. Background Technology

[0002] The bundled tube monitoring system is an important device used in coal mine safety production to monitor the composition and concentration of underground gas in real time. It uses pump stations to transport underground gas samples to the surface for analysis, providing key data support for gas prevention and ventilation management.

[0003] In actual operation, due to the high humidity and significant temperature changes in the underground environment, condensate easily forms inside the tube bundle. If it is not drained in time, the condensate will enter the pump station with the airflow, which will not only contaminate the gas sample and interfere with the accuracy of the monitoring data, but may also damage the precision components inside the pump station, leading to an increased equipment failure rate. Currently, the commonly used water drainage methods mostly rely on manual periodic operation, which has problems such as low efficiency, untimely response, and high labor intensity. It is difficult to achieve real-time, automatic, and reliable drainage control, which affects the continuous and stable operation of the system.

[0004] Therefore, to address the above issues, a lever-type automatic water discharge device for bundled tube monitoring pump stations can be designed. This device employs a lever-type structure design, using the weight of accumulated water to trigger mechanical action for automatic drainage and reset. The entire process requires no electric drive or external control signals; it relies solely on the energy conversion of the mechanical structure itself to complete the action cycle. It is low-cost, effectively replaces manual operation, and improves the reliability and data accuracy of the bundled tube monitoring system. Utility Model Content

[0005] To overcome the shortcomings of the current bundled tube monitoring system, which mainly adopts the manual timed water release mode, such as the limited operation frequency due to the work shift schedule, the response delay leading to water accumulation, and the equipment malfunction and shutdown caused by human error, it is difficult to meet the requirements of continuous and stable system operation.

[0006] The technical solution of this utility model is as follows: a lever-type automatic water discharge device for a bundled tube monitoring pump station, including a base and two sets of support frames symmetrically fixedly installed on the upper end of the base. A connecting seat is provided at the upper end of the support frame, and a water storage tank is provided between the two sets of connecting seats. Two sets of connecting shafts are symmetrically welded to the periphery of the water storage tank. The two sets of connecting shafts are rotatably connected to the two sets of connecting seats respectively. A check valve is provided at the lower end of the water storage tank near the tail end. Two sets of air connectors are provided at the upper end of the water storage tank. A support component and a trigger component are provided at the upper end of the base. The support component is near the front end of the water storage tank, and the trigger component is near the rear end of the water storage tank.

[0007] Preferably, the connecting seats are supported and installed using a support frame. The water storage tank is rotatably installed between two sets of connecting seats by setting the connecting seats to cooperate with the connecting shaft. The pump station can be connected by conventional hoses through two sets of air passage connectors to form a through flow path with one inlet and one outlet. The water storage tank is supported by a support mechanism. When operation is carried out, the water-containing airflow enters the interior of the water storage tank, the water is retained in the water storage tank, and the airflow is discharged. When the water storage tank contains a certain amount of water, the weight of the water presses the water storage tank to rotate around the connecting shaft, causing the check valve to contact and open the trigger component, discharging the water in the water storage tank. Then the water storage tank resets and continues to collect water, completing one water discharge operation. The check valve can effectively prevent the problem of monitoring data distortion caused by gas backflow during the water discharge process.

[0008] Preferably, when the water tank is empty, the height of the front end of the water tank is higher than that of the rear end.

[0009] Preferably, the connecting shaft is located near the tail end of the water tank.

[0010] Preferably, the support assembly includes a column welded to the upper end of the base, and a U-shaped bracket welded to the upper end of the column.

[0011] Preferably, the triggering component includes a supporting steel bar welded to the upper end of the base, and a triggering rubber block is fixedly connected to the upper end of the supporting steel bar.

[0012] Preferably, the water tank has an end cap at the rear end, and the end cap is connected and fixed to the water tank by fasteners.

[0013] Preferably, the rear end of the water tank has a groove, and the end cap is provided with a sealing ring that is interference-fitted with the groove on the side corresponding to the water tank.

[0014] The beneficial effects of this utility model are: The water storage cylinder is supported by a column and bracket. When the cylinder is empty, it is in a stable position with the front end slightly higher than the rear end. When a gas sample containing water enters the cylinder, the water is retained inside due to gravity and flows to the rear end. The gas, freed from water, exits the cylinder and enters the subsequent monitoring system. After a certain mass of water is stored inside the cylinder, the weight of the water causes the cylinder to rotate via a connecting shaft, resulting in tilting. This causes the check valve at the rear end of the cylinder to descend and trigger the rubber block to open, releasing the water. At this point, the weight at the rear end of the cylinder decreases, and under the balance of gravity, the front end of the cylinder rotates back to the bracket, completing one automatic drainage cycle. This ensures timely drainage of water. The entire process requires no electric drive or external control signals; it relies solely on the energy conversion of the mechanical structure to complete the cycle. It is low-cost, effectively replaces manual operation, and improves the reliability and data accuracy of the bundled tube monitoring system. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1 This utility model provides an embodiment of a lever-type automatic water discharge device for a bundled tube monitoring pump station, including a base 1 and two sets of support frames 101 symmetrically fixedly installed on the upper end of the base 1. A connecting seat 102 is provided at the upper end of each support frame 101. A water storage tank 2 is provided between the two sets of connecting seats 102. Two sets of connecting shafts 201 are symmetrically welded to the periphery of the water storage tank 2, and the two sets of connecting shafts 201 are rotatably connected to the two sets of connecting seats 102 respectively. A check valve 7 is provided near the tail end of the water storage tank 2. Two sets of air connectors 4 are provided at the upper end of the water storage tank 2. A support component and a trigger component are provided at the upper end of the base 1. The support component is near the front end of the water storage tank 2, and the trigger component is near the rear end of the water storage tank 2. The connecting seat 102 is supported by the support frames 101. The water tank 2 is rotatably installed between two sets of connecting seats 102 and connecting shaft 201. Two sets of air connectors 4 allow for connection to the pump station using conventional hoses, forming a through-flow path. The water tank 2 is supported by a support mechanism. During operation, water-containing airflow enters the interior of the water tank 2, where water is retained, and the airflow is discharged. When the water tank 2 contains a certain amount of water, its own weight causes it to rotate around the connecting shaft 201, causing the check valve 7 to contact and open with the trigger component, discharging the water from the tank 2. The water tank 2 then resets and continues to collect water, completing one water discharge operation. The check valve 7 effectively prevents data distortion caused by backflow of gas during water discharge.

[0018] Please see Figure 1 and Figure 2 In this embodiment, when the water tank 2 is empty, the height of the front end of the water tank 2 is higher than its rear end; the connecting shaft 201 is close to the rear end of the water tank 2; thus, a dynamic balance mechanism is constructed through the gravitational potential energy difference, and the torque conversion is achieved by using the weight of the accumulated water to drive the attitude adjustment of the water tank 2, ensuring that a controllable tilting action is triggered when the accumulated water reaches a critical point, forming a passive automatic adjustment closed-loop control logic, effectively avoiding the lag risk of traditional manual intervention; the supporting component includes a column 501 welded to the upper end of the base 1, and the upper end of the column 501 A bracket 502 with a U-shaped structure is welded on; the bracket 502 works in conjunction with the column 501 to provide axial support for the front end of the water tank 2; the triggering component includes a supporting steel bar 601 welded to the upper end of the base 1, and a triggering rubber block 602 is fixedly connected to the upper end of the supporting steel bar 601; the triggering rubber block 602 is installed through the supporting steel bar 601, and the triggering rubber block 602 achieves soft contact opening and closing control with the check valve 7 during the drainage action, which not only ensures the reliability of mechanical signal transmission, but also avoids structural damage caused by rigid collisions and improves the durability of the device.

[0019] Please see Figure 3 and Figure 4 In this embodiment, an end cap 3 is provided at the rear end of the water storage cylinder 2. The end cap 3 is connected and fixed to the water storage cylinder 2 by fasteners. A groove 202 is provided at the rear end of the water storage cylinder 2. A sealing ring 301 that is interference-fitted with the groove 202 is provided on the side of the end cap 3 corresponding to the water storage cylinder 2. The end cap 3, which is connected and fixed by fasteners, is easy to disassemble and install later, and it is convenient to clean and maintain the inside of the water storage cylinder 2. The sealing ring 301 and the groove 202 ensure the sealing of the connection between the end cap 3 and the water storage cylinder 2.

[0020] When working, the two sets of air connectors 4 near the upper end of the water tank 2 are used to connect to the gas delivery system of the monitoring pump station. The air connector 4 near the front end of the water tank 2 serves as the air inlet, and the air connector 4 at the rear end of the water tank 2 serves as the air outlet, forming a through gas flow path with the inner cavity of the water tank 2. The water storage cylinder 2 is supported by the column 501 and the bracket 502. When there is no water in the water storage cylinder 2, the water storage cylinder 2 is in a stable state with the front end slightly higher than the rear end. When a gas sample containing water enters the water storage cylinder 2, the water will be retained inside the water storage cylinder 2 under the action of gravity and flow to the rear end of the water storage cylinder 2. The gas that has been dehydrated is discharged from the water storage cylinder 2 and enters the subsequent monitoring system. When the water tank 2 has stored a certain amount of water, the weight of the water causes it to rotate via the connecting shaft 201, causing it to tilt. This causes the check valve 7 at the tail end of the water tank 2 to descend and contact the trigger block 602 to open, releasing the water from the tank. As the weight at the tail end of the water tank 2 decreases, the front end of the water tank 2 rotates back to the bracket 502 under the influence of gravity, completing one automatic drainage cycle. This ensures timely drainage of the water. The entire process requires no electric drive or external control signals; it relies solely on the energy conversion of the mechanical structure itself to complete the cycle. It is low-cost, effectively replaces manual operation, and improves the reliability and data accuracy of the bundle tube monitoring system.

[0021] Through the above steps, the pump station can be connected by conventional hoses through two sets of air connectors 4, forming a through flow path with one inlet and one outlet. After the water-containing airflow enters the water storage tank 2, the water is retained and the airflow is discharged. When the water accumulates to a certain amount, the water storage tank 2 rotates around the connecting shaft 201 due to its own weight, causing the check valve 7 to contact and open with the trigger component on the base 1, discharging the accumulated water. After that, the water storage tank 2 resets and continues to collect water, completing the cycle of water discharge. The entire process does not require electric drive or external control signals, but only relies on the energy conversion of the mechanical structure itself to complete the action cycle. It is low in cost and can effectively replace manual water discharge operations, improving the reliability and data accuracy of the bundle tube monitoring system. This solves the problem that the current bundle tube monitoring system mainly uses a manual timed water discharge mode, which has systemic shortcomings such as the operation frequency being limited by the work shift schedule, response delay leading to water retention, and human error causing equipment to malfunction and shut down, making it difficult to meet the requirements for continuous and stable system operation.

[0022] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
