Description

Technical Field

[0001] This invention relates to the field of water level monitoring technology, specifically to a water level detection and control device for forest fire-fighting water storage tanks. Background Technology

[0002] Monitoring the water level in forest fire prevention reservoirs is a key measure to ensure sufficient emergency water supply for forest fire prevention and improve firefighting efficiency. The water level in the reservoirs is directly related to the water supply capacity during a fire. Especially during the dry season, a large amount of water in the reservoirs evaporates, causing the water level to fall below the standard value. The dry summer is also the peak season for forest fires. Therefore, water monitoring devices are needed to monitor the water level in the reservoirs.

[0003] For example, a forest fire prevention water storage tank water volume monitoring device, with announcement number CN217276408U, relates to the field of forest fire prevention technology. This device includes a fixing device fixedly installed on the ground. The fixing device includes a fixing base, and a fixing block A is fixedly installed on the right end of the fixing base. Two sets of clamping rods are hinged to the fixing block A, clamping a monitoring rod in the middle. A bidirectional threaded rod is threaded to the right end of the two sets of clamping rods, and a rotating handle A is fixedly installed on the bidirectional threaded rod. The bottom of the monitoring rod is located at the bottom of the water storage tank. A floating block is fixedly connected to the right end of the monitoring rod via a steel cable. The floating block is located below the water surface. When the water level drops, the buoyancy of the water on the floating block decreases, and the steel cable slowly contracts. When the warning water level is reached, a warning light illuminates, preventing impurities on the water from affecting the floating block.

[0004] Common methods for monitoring water levels in existing water tanks include water gauge observation, pressure level gauges, and ultrasonic rangefinders. However, for outdoor forest fire prevention water storage tanks, when using pressure level gauges for monitoring, the water storage tanks are affected by wind or debris falling in, which causes fluctuations in the water flow. When the water flows rapidly, the dynamic pressure may be superimposed on the static pressure, causing the measured value to deviate from the true water level, thus affecting the measurement accuracy of the pressure level gauge. In addition, the operating temperature range of pressure level gauges is generally -25°C to 70°C. When the external ambient temperature is below -25°C, it will also affect the normal operation of the pressure level gauge. Summary of the Invention

[0005] The purpose of this invention is to provide a water level detection and control device for forest fire-fighting water storage tanks, in order to solve the problem that when the water in the tank flows rapidly, the measured value deviates from the true water level, thereby affecting the measurement accuracy of the pressure level gauge, and that when the external ambient temperature is below -25°C, it also affects the normal operation of the pressure level gauge.

[0015] Preferably, the inner rod is slidably connected to the slide groove, the inner sides of the two inner rods are fixedly connected to the same inner cylinder, the inner wall of the inner cylinder is slotted and fixedly installed with an electric heating wire, and the bottom of the inner cylinder is symmetrically fixedly connected with scrapers, which are in contact with the inner wall of the sleeve.

[0016] By adopting the above technical solution, the rise of the vertical rod will also drive the rise of the inner rod, which in turn drives the rise of the inner cylinder. The electric heating wire inside the inner cylinder facilitates the heating of the water outside the pressure level gauge body.

[0017] Preferably, an mounting plate and a battery pack are fixedly installed on the other side of the upper part of the vertical cylinder. The battery pack is located above the mounting plate. The auxiliary component includes a mounting box fixedly installed with the vertical cylinder. A fixing plate is fixedly installed inside the lower part of the mounting box.

[0021] Preferably, an upper plate is fixedly connected to the outer side of the vertical cylinder. The upper plate is located above the mounting box.

[0022] By adopting the above technical solution, the servo motor drives the rotating rod to rotate, and the rotating rod drives the scraper to rotate, which facilitates the scraping and cleaning of the top of the solar panel.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up protective components and utilizing the cooperative characteristics of the sliding rod, sliding column, and clamping block, the stability of the pressure level gauge body can be improved when subjected to water flow fluctuations near or far on the outside of the pressure level gauge body. Furthermore, the flexible contact plate responds to the influence of water flow fluctuations, avoiding the situation where parts are more easily damaged by hard impacts when using direct fixing methods, and reducing the deviation of monitoring results. Simultaneously, the clamping block presses against the fixing rod, and the sliding column drives the clamping block to move in a spiral motion, ensuring that the clamping block's retraction continues for a period of time, preventing rapid separation between the clamping block and the fixing rod, further maintaining the overall stability of the pressure level gauge body. At the same time, the slow movement of the inner cylinder driven by the sliding rod heats the area around the pressure level gauge body, maintaining its normal operation. Specific details are as follows: By incorporating protective components, when the contact plate is affected by water flow fluctuations near or far from the pressure level gauge body, it will move, causing the contact plate to stretch or compress spring one. This causes the contact plate to move two push blocks, resulting in the left or right push block pressing against the inclined surface of the trapezoidal block. The trapezoidal block then causes the vertical rod and side block to rise. The collar limits the vertical rod, and the side block compresses spring two. The rising vertical rod causes the top block to move, pressing against the inclined surface of the inclined block. The limiting strip limits the inclined block, causing it to move linearly and push the sliding column. The limiting block slides inside the helical groove, causing the sliding column to move and rotate simultaneously. The sliding column acts on the torsion spring, and the sliding column drives the connecting... The movement of the rod and the clamping block causes the clamping block to press against the outside of the fixed rod, thereby enhancing the overall stability of the pressure level gauge body. The retraction of the clamping block will continue for a period of time, preventing the clamping block from quickly separating from the vertical rod. The rise of the vertical rod will also drive the inner rod to rise. The inner rod slides inside the groove and drives the inner cylinder to rise. The electric heating wire inside the inner cylinder facilitates the heating treatment of the water outside the pressure level gauge body. The inner cylinder will also drive the scraper to scrape and clean the inner wall of the sleeve, thereby reducing the residue of debris on the sleeve, maintaining the normal flow of water, and improving the monitoring accuracy of the pressure level gauge body. By setting up auxiliary components, the float plate is positioned at the water surface of the pool. As the water level drops, the float plate descends, driving the guide rod to move. The guide rod then drives the moving plate to descend, compressing the spring three until the upper and lower contacts at the bottom of the moving plate make contact. At this point, the alarm light is in a closed-circuit state and will illuminate to alert staff and facilitate water replenishment. Furthermore, by activating the servo motor, the rotating rod rotates, which in turn rotates the scraper, facilitating the scraping and cleaning of the top of the solar panels, reducing the residue of leaves and debris, and maintaining the power generation efficiency of the solar panels.

[0027] Please see Figure 1 - Figure 3 The present invention provides a technical solution: a water level detection and control device for a forest fire-fighting water storage tank, comprising a vertical cylinder 1 and a fixed rod 2 fixedly installed on the top surface inside the vertical cylinder 1, wherein a pressure water level gauge body 3 is fixedly installed at the bottom end of the fixed rod 2.

A slot is opened on the lower outer side of the sleeve 9 to keep the water flow smoothly.

[0029] like Figure 1 and Figure 3 - Figure 9 As shown, the protective component 7 includes two bent plates 71 symmetrically fixedly connected to the lower part of the outer side of the sleeve 9. There are no fewer than two bent plates 71, and more can be set as needed. The bottom end of the bent plate 71 is fixedly connected to the same fixing ring 72. A slide rod 73 is symmetrically slidably installed inside the fixing ring 72. One end of the slide rod 73 is fixedly connected to a contact plate 74, and the top of the other end of the slide rod 73 is fixedly connected to two push blocks 76.

[0030] A vertical rod 77 is slidably installed inside the bent plate 71. A trapezoidal block 78 is fixedly connected to the bottom end of the vertical rod 77. A fixing cylinder 715 is symmetrically fixedly installed on the lower outer side of the fixing rod 2. A pressing block 722 is slidably installed on one side inside the fixing cylinder 715. When the pressing block 722 presses against the fixing rod 2, it is convenient to improve the overall support strength and stability of the pressure level gauge body 3.

[0031] The outer sleeve of the slide rod 73 has a spring 75. The two ends of the spring 75 are fixedly connected to the fixing ring 72 and the contact plate 74 respectively. The spring 75 is used to assist the sliding reset of the contact plate 74. The trapezoidal block 78 is located between the two push blocks 76, and the two push blocks 76 abut against the two inclined surfaces at the bottom of the trapezoidal block 78 respectively. A side block 79 is fixedly connected to the side of the trapezoidal block 78 near the sleeve 9. A spring 710 is fixedly connected between the side block 79 and the bending plate 71. A collar 711 is also fixedly connected to the outer side of the sleeve 9.

[0032] The vertical rod 77 is slidably connected to the collar 711. The number of collars 711 and the vertical rod 77 are the same. The outer side of the vertical rod 77 is fixedly connected to the top block 712 and the inner rod 724 from top to bottom. The upper outer side of the sleeve 9 is symmetrically and slidably installed with the inclined block 713. The inclined surface of the top block 712 abuts against the inclined surface of the inclined block 713. The top of the inclined block 713 is fixedly connected with the limit strip 714.

[0033] The limiting strip 714 is slidably connected to the sleeve 9. A side ring body 716 is fixedly connected to one side of the inside of the fixed cylinder 715. A sliding column 718 is slidably connected to the other side of the inside of the fixed cylinder 715. The sliding column 718 is rotatably connected to the inclined block 713. A torsion spring 717 is fixedly connected between the side ring body 716 and the sliding column 718.

[0034] A limiting block 719 is fixedly connected to the top outer side of the sliding column 718. A helical groove 720 is provided on the inner wall of the fixed cylinder 715. The limiting block 719 is slidably connected to the helical groove 720. The limiting block 719 slides inside the helical groove 720, so that the sliding column 718 will also rotate when sliding. A connecting rod 721 is fixedly connected to the side of the sliding column 718 away from the inclined block 713. The connecting rod 721 is rotatably connected to the pressing block 722. Sliding grooves 723 are symmetrically provided on the outer side of the sleeve 9.

[0035] The inner rod 724 is slidably connected to the slide groove 723. The inner sides of the two inner rods 724 are fixedly connected to the same inner cylinder 725. The inner wall of the inner cylinder 725 is slotted and fixedly installed with an electric heating wire 726. The bottom of the inner cylinder 725 is symmetrically fixedly connected with scraper 727, which is in contact with the inner wall of the sleeve 9.

[0036] Example 1: As Figure 3 - Figure 9As shown, when the contact plate 74 is affected by the water flow fluctuations that are close to or far from the pressure level gauge body 3, the contact plate 74 will move. The contact plate 74 stretches or compresses the spring 75, and the contact plate 74 drives the two push blocks 76 to move, so that the left or right push block 76 presses the inclined surface of the trapezoidal block 78. The trapezoidal block 78 drives the vertical rod 77 and the side block 79 to rise. The collar 711 limits the vertical rod 77, the side block 79 compresses the spring 710, and the rise of the vertical rod 77 will drive the top block 712 to move. The top block 712 presses the inclined surface of the inclined block 713, and the limiting strip 714 limits the inclined block 713, so that the inclined block 713 moves linearly and pushes the slide column 718 to move.

[0037] The limiting block 719 slides inside the helical groove 720, causing the slide column 718 to move and rotate simultaneously. The slide column 718 acts on the torsion spring 717, and the slide column 718 drives the connecting rod 721 and the pressing block 722 to move, so that the pressing block 722 presses against the outside of the fixed rod 2, thereby facilitating the overall stability of the pressure level gauge body 3. The retraction of the pressing block 722 will continue for a period of time, and there will be no situation where the pressing block 722 and the fixed rod 2 separate quickly.

[0038] The rise of the vertical rod 77 also causes the inner rod 724 to rise. The inner rod 724 slides inside the slide groove 723 and causes the inner cylinder 725 to rise. The electric heating wire 726 inside the inner cylinder 725 facilitates the heating treatment of the water outside the pressure level gauge body 3. The inner cylinder 725 also drives the scraper 727 to scrape and clean the inner wall of the sleeve 9, thereby reducing the residue of debris on the sleeve 9, maintaining the normal flow of water, and improving the monitoring accuracy of the pressure level gauge body 3.

[0039] like Figure 1 and Figure 10 - Figure 12 As shown, an auxiliary component 8 is provided on one side of the upper part of the vertical cylinder 1, and a mounting plate 5 and a battery pack 6 are fixedly installed on the other side of the upper part of the vertical cylinder 1. The battery pack 6 is located above the mounting plate 5 and is used to power the entire device. The auxiliary component 8 includes a mounting box 81 fixedly installed with the vertical cylinder 1. A fixing plate 82 is fixedly installed inside the lower part of the mounting box 81. A lower contact 83 is fixedly installed on the top of the fixing plate 82. An alarm light 84 is fixedly installed on the lower part of the outer side of the mounting box 81. When the upper contact at the bottom of the moving plate 86 contacts the lower contact 83, the alarm light 84 is in a closed state and will light up as a warning. A guide rod 85 is vertically slidably connected inside the lower contact 83.

[0040] A movable plate 86 is fixedly connected to the top of the guide rod 85, and an upper contact is fixedly installed at the bottom of the movable plate 86. A spring 87 is sleeved on the outside of the guide rod 85, and the two ends of the spring 87 are fixedly connected to the fixed plate 82 and the movable plate 86 respectively. A float plate 88 is fixedly connected to the bottom of the guide rod 85 through the mounting box 81.

[0041] An upper plate 89 is fixedly connected to the outside of the vertical cylinder 1. The upper plate 89 is located above the mounting box 81. A servo motor 810 is fixedly installed on the top of the upper plate 89. A rotating rod 811 is fixedly connected to the upper contact of the servo motor 810. A scraper 812 is fixedly connected to the top of the rotating rod 811. The scraper 812 is in contact with the top surface of the solar panel 4. The top surface of the solar panel 4 is scraped and cleaned by the scraper 812, thereby reducing the obstruction of debris.

[0042] Example 2: Figure 10 - Figure 12 As shown, the float plate 88 is positioned at the surface of the water tank. As the water level drops, the float plate 88 descends, causing the guide rod 85 to move. The guide rod 85 then causes the moving plate 86 to descend, compressing the spring 87 until the upper contact point and lower contact point 83 at the bottom of the moving plate 86 come into contact. At this time, the alarm light 84 is in a closed-circuit state and will illuminate to alert staff and facilitate water replenishment. Furthermore, by activating the servo motor 810, the servo motor 810 drives the rotating rod 811 to rotate, which in turn drives the scraper 812 to rotate, facilitating the scraping and cleaning of the top of the solar panel 4, reducing the residue of leaves and debris, and maintaining the power generation efficiency of the solar panel 4.

[0043] Working principle: When using this device, firstly, as... Figure 1 - Figure 12As shown, when the contact plate 74 is affected by water flow fluctuations near or away from the pressure gauge body 3, it will move. The contact plate 74 will move the two push blocks 76, the trapezoidal block 78 will move the vertical rod 77 and the side block 79, the vertical rod 77 will move the top block 712, the inclined block 713 will move linearly and push the sliding column 718 to move, the limiting block 719 will slide inside the spiral groove 720, so that the sliding column 718 moves and rotates at the same time, and the sliding column 718 will move the connecting rod 721 and the pressing block 722, so that the pressing block 722 will press against the outside of the fixed rod 2, thereby facilitating the overall stability of the pressure gauge body 3. The rise of the vertical rod 77 will also drive the inner rod 724 to rise. The inner rod 724 will slide inside the sliding groove 723, and the inner rod 724 will drive the inner cylinder 725 to rise. The electric heating wire 726 inside the inner cylinder 725 facilitates the heating of the inner cylinder 725. The water outside the pressure level gauge body 3 is heated, and the inner cylinder 725 also drives the scraper 727 to scrape and clean the inner wall of the sleeve 9, thereby reducing the residue on the sleeve 9 and maintaining the normal flow of water. The float plate 88 is at the liquid level of the pool. As the liquid level in the pool drops, the float plate 88 will descend. The float plate 88 drives the guide rod 85 to move, and the guide rod 85 drives the moving plate 86 to descend. The moving plate 86 compresses the spring 87 until the upper contact point and lower contact point 83 at the bottom of the moving plate 86 contact each other. The alarm light 84 is in a closed state. At this time, the alarm light 84 will light up to warn the staff in time so that they can perform water replenishment operation. By starting the servo motor 810, the servo motor 810 drives the rotating rod 811 to rotate. The rotating rod 811 drives the scraper 812 to rotate, which facilitates the scraping and cleaning of the top of the solar panel 4 and maintains the power generation efficiency of the solar panel 4.
