Description

Technical Field

[0001] The utility model relates to the technical field of water level gauges, in particular to a bubble type water level gauge. Background Art

[0002] A bubble water level gauge is an instrument that determines the water level by measuring the hydrostatic pressure at a fixed point underwater. Its typical feature is that during operation, gas is blown into the water through a blowpipe, so it is called a bubble water level gauge. The bubble water level gauge is small in size and has the characteristics of convenient installation and maintenance, flexible operation and networking, stable and reliable operation, and high measurement accuracy.

[0003] However, since the bubble water level gauge measures the liquid level by detecting the pressure required for bubbles to rise in water, in a dynamic water flow environment such as a river, it may be interfered by factors such as water surface waves, foam, and water flow changes. These factors will cause the water surface to rise and fall, affecting the pressure transmission of the bubbles, thereby causing measurement errors. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is: aiming at the above problems, to provide a bubble type water level gauge.

[0005] The technical solution adopted by the utility model is: a bubble type water level gauge, characterized by comprising:

[0006] A main device, including a gas source assembly, a pressure measurement assembly, and a control and data output assembly. An outer shell is provided outside the main device, and the outer shell is installed on the bank of the water body to be detected;

[0007] An isolation cylinder, which is arranged vertically in the detected water body. The top of the isolation cylinder is higher than the water surface of the detected water body. An inlet is provided at the bottom of the isolation cylinder, and the isolation cylinder can isolate the water body inside from the disturbance generated by the external water flow;

[0008] A telescopic connecting rod, with two ends respectively connected to the outer shell and the isolation cylinder, and the telescopic connecting rod can adjust the distance between the isolation cylinder and the outer shell;

[0009] A blowpipe, whose connecting end passes through the outer shell and is connected to the gas source assembly, and the blowing end of the blowpipe extends into the water body inside the isolation cylinder.

[0010] In some embodiments, the isolation cylinder includes a plurality of isolation sheets and an elastic isolation plate. The plurality of isolation sheets are slidably inserted and enclosed adjacent to each other to form a cylindrical structure. The bottom of the plurality of isolation sheets is connected to the elastic isolation plate. An inlet is provided at the middle position of the elastic isolation plate. A plurality of adjusting components are arranged inside the isolation cylinder. The adjusting components are arranged along the length direction of the isolation cylinder. The plurality of adjusting components can drive the isolation sheets to expand or contract to adjust the diameter of the isolation cylinder. The elastic isolation plate can adapt to the diameter change of the isolation cylinder through elastic action.

[0011] In some embodiments, the adjusting component includes a sleeve, an operating rod and an adjusting screw. A pair of sleeves are respectively connected to a set of opposite isolation sheets. The two ends of the operating rod are respectively connected with the adjusting screws. The adjusting screws at both ends are respectively threadedly connected with a pair of sleeves. Reverse threads are made on the adjusting screws at both ends.

[0012] In some embodiments, the isolation sheet is provided with a mounting hole in the radial direction. A double-layer filter screen is provided at the mounting hole. A water filtering membrane is arranged between the double-layer filter screens.

[0013] In some embodiments, a conical water inlet guiding ring is connected to the inlet of the elastic isolation plate.

[0014] In some embodiments, the telescopic connecting rod includes a first rod body and a second rod body. One end of the first rod body is fixedly connected to the outer wall of the housing.

[0016] The beneficial effects of the present utility model are:

[0017] 1. Connect the housing of the main device to the isolation cylinder through a telescopic connecting rod, so that the isolation cylinder can be fixedly arranged in the water body to be detected, and the arrangement position of the isolation cylinder can be adjusted by using the telescopic connecting rod. The blowing end of the blowing pipe extends into the water body inside the isolation cylinder. The isolation cylinder is used to separate part of the detected water body. The water flow enters from the bottom of the isolation cylinder, blocking the direct transmission of surface waves, foam, etc. above the blowing pipe.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model will be further described below in conjunction with specific embodiments.

[0030] Combined with Figures 1 to 5 As shown, this embodiment is a bubble type water level gauge, which includes a main device 1, an isolation cylinder 3, a telescopic connecting rod 2 and a blowing pipe 12. The main device 1 includes an air source component, a pressure measurement component, and a control and data output component. An outer shell 11 is provided outside the main device 1, and the outer shell 11 is installed on the bank of the water body to be detected. The outer wall of the outer shell 11 is connected to the isolation cylinder 3 through the telescopic connecting rod 2, and the telescopic connecting rod 2 can adjust the distance between the isolation cylinder 3 and the outer shell 11. The isolation cylinder 3 is vertically arranged in the detection water body. The top of the isolation cylinder 3 is higher than the water surface of the detection water body, and the bottom of the isolation cylinder 3 is below the water surface of the detection water body. An inlet 61 is provided at the bottom of the isolation cylinder 3, and the isolation cylinder 3 can isolate the internal water body from the disturbance generated by the external water flow. The connecting end of the blowing pipe 12 passes through the outer shell 11 and is connected to the air source component, and the blowing end of the blowing pipe 12 extends into the water body inside the isolation cylinder 3.

[0031] Further, the air source component includes an air pump and a gas storage cylinder, and the main device 1 is equipped with a corresponding power supply. In this embodiment, the outer shell 11 is fixedly installed on the bank of the river through an anchor rod or an expansion bolt.

[0032] Further, the blowing end of the blowing pipe 12 penetrates through the outer wall of the isolation cylinder 3 and extends into the isolation cylinder 3, or the blowing end of the blowing pipe 12 extends from the top of the isolation cylinder 3 into the isolation cylinder 3.

[0033] In some embodiments, the isolation cylinder 3 includes multiple isolation sheets 31 and an elastic isolation plate 6. The isolation sheets 31 are in an arc structure, and multiple isolation sheets 31 are slidably inserted and enclosed adjacent to each other to form a cylindrical structure. The bottom of multiple isolation sheets 31 is connected with an elastic isolation plate 6, and an inlet 61 is provided at the middle position of the elastic isolation plate 6. Multiple sets of adjusting components 4 are arranged inside the isolation cylinder 3. The adjusting components 4 are arranged along the length direction of the isolation cylinder 3. Multiple adjusting components 4 can adjust the diameter of the isolation cylinder 3 by driving the isolation sheets 31 to expand or contract. The elastic isolation plate 6 can adapt to the diameter change of the isolation cylinder 3 through elastic action. The elastic isolation plate 6 is fixedly connected to multiple isolation sheets 31. Since the elastic isolation plate 6 has elasticity, it will not affect the normal expansion or contraction of multiple isolation sheets 31, and can play a role in isolating the river water.

[0034] Further, asFigure 2 As shown in the figure, the adjusting assembly 4 includes a sleeve 41, an operating rod 7 and an adjusting screw 42. A pair of sleeves 41 are respectively connected to a set of opposite spacer plates 31. The pair of sleeves 41 are arranged coaxially. Both ends of the operating rod 7 are respectively connected with an adjusting screw 42. The adjusting screws 42 at both ends are respectively in threaded connection with the pair of sleeves 41. The adjusting screws 42 at both ends are provided with threads in opposite directions. The axis lines of the sleeve 41 and the adjusting screw 42 intersect with the axis line of the isolation cylinder 3. By rotating the adjusting screw 42 with the operating rod 7, due to the threaded connection between the adjusting screw 42 and the sleeve 41, the distance between a set of spacer plates 31 can be adjusted, and the operation is simple and convenient.

[0035] Further, as Figure 3 shown in Figure 4 the figure, each spacer plate 31 is provided with a mounting hole 311 in the radial direction, so that the spacer plate 31 is in a frame shape. A double-layer filter screen 5 is arranged at the mounting hole 311. A water filtering membrane 51 is arranged between the double-layer filter screens 5. The water filtering membrane 51 can play a role in filtering water. The filter screen 5 also has the functions of supporting the water filtering membrane 51 and filtering the river water. It can not only facilitate the river water to enter the isolation cylinder 3, but also prevent the water surface waves, foam, etc. outside the isolation cylinder 3 from directly transmitting into the isolation cylinder 3.

[0036] Further, as Figure 3 shown in Figure 4 the figure, the water inlet 61 of the elastic isolation plate 6 is circular or square. A conical water inlet guiding ring 611 is connected to the water inlet 61 of the elastic isolation plate 6. The water inlet guiding ring 611 is located below the elastic isolation plate 6. The water inlet guiding ring 611 is coaxially bonded to the water inlet 61 of the elastic isolation plate 6 by strong glue. The shape and structure of the water inlet guiding ring 611 can not only facilitate the water flow to enter, but also prevent the water flowing rapidly below the river water from directly entering the isolation cylinder 3, thereby affecting the air outlet of the air blowing pipe 12.

[0037] In some embodiments, as Figure 5 shown in

[0038] the figure, the telescopic connecting rod 2 includes a first rod body 21 and a second rod body 22. One end of the first rod body 21 is fixedly connected to the outer wall of the housing 11 through a bolt. The other end of the first rod body 21 is inserted into the second rod body 22. The end of the second rod body 22 far from the first rod body 21 is fixedly connected to the outer wall of the isolation cylinder 3 through a bolt. The first rod body 21 and the second rod body 22 are connected by telescopic adjustment to change the connection length, and the first rod body 21 and the second rod body 22 are fixedly connected by a fixing bolt 23 to fix the connection length. A plurality of through holes through which the fixing bolt 23 can pass are provided along the length direction on the first rod body 21 and the second rod body 22, so as to facilitate adjusting the connection length between the first rod body 21 and the second rod body 22 and ensure the fixing effect between the first rod body 21 and the second rod body 22.By loosening the fixing bolt 23, the first rod body 21 and the second rod body 22 are adjusted to expand and contract. After adjusting to the appropriate length, just tighten the fixing bolt 23. The fixing bolt 23 can be a butterfly screw for easy operation by the staff. Furthermore, by adjusting the length of the telescopic connecting rod 2, the position of the isolation cylinder 3 is adjusted.

[0039] Embodiment The implementation principle of a bubble type water level gauge is as follows:

[0040] First, install the main device 1 of the water level gauge and its outer shell 11 at the position to be measured on the river bank. The isolation cylinder 3 needs to be installed vertically. One end of the isolation cylinder 3 is above the water surface, and one end of the isolation cylinder 3 with the elastic isolation plate 6 is below the water surface. During this period, the telescopic connecting rod 2 can be used to adjust the position of the isolation cylinder 3, and multiple sets of adjustment components 4 can be used to adjust the diameter of the isolation cylinder 3. Then, install the blowing end of the air blowing pipe 12 inside the isolation cylinder 3. In this way, the water flow will enter from below the isolation cylinder 3, thus blocking the direct transmission of water surface waves, foam, etc. above the air blowing pipe 12. In a dynamic water flow environment such as a river, the interference of factors such as water surface waves, foam, and water flow changes on the air outlet end of the air blowing pipe 12 is effectively reduced, and the influence on the pressure transmission of the bubbles is largely avoided, thereby causing measurement errors, and finally the measurement accuracy of the bubble water level gauge is effectively improved.

[0041] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
