Description

Technical Field

[0001] The utility model belongs to the field of hydrological measurement equipment, and relates to a hydrological emergency mobile measurement equipment, in particular to a mobile and portable box-type hydrological emergency current-measuring cableway. Background Technique

[0002] Hydrological emergency measurement is an important means to timely master the river flood information and prevent and resolve the flood disaster risk. In order to timely master the flood flow information, it is generally necessary to carry out cross-river measurement on the river section to be measured. Due to the uncertainty of the flood occurrence time and location, there may not be hydrological cross-river facilities built on the river section to be measured. Usually, water-crossing structures such as bridges can be used to cross the river. There are two disadvantages in the method of crossing the river by using water-crossing structures such as bridges. One is that it is not certain that water-crossing structures such as bridges with suitable heights can be found on all measurement river sections. The other is that when the flood water flow velocity is relatively large and the measurement equipment is a moving ADCP, the ADCP is subject to a large water flow resistance in the downstream direction in the water. Often, multiple people need to cooperate to pull it, which consumes a lot of physical strength and poses a safety hazard at the same time.

[0003] Therefore, when a bridge cannot be found or the water flow velocity is relatively large, setting up a hydrological emergency current-measuring cableway to cross the river is a safe and labor-saving method. Currently, there are many types of hydrological emergency current-measuring cableways. Generally speaking, they have the following two major disadvantages: one is the low mobility. Generally, cableway supports need to be set up to carry the river-crossing steel cable. The cableway supports generally need to be installed by civil engineering or buried in the ground. Some need to set up stay cables to improve the stability, and the river-crossing steel cable needs to be customized with a specific length according to the river width, which is not conducive to repeated use of multiple sections; the other is the lack of portability. The hydrological cableways erected by traditional methods often have a large volume and numerous scattered parts, and need to be processed and assembled on site. The installation, disassembly and transportation are all cumbersome and time-consuming.

[0004] Through comprehensive analysis, it is considered that the existing hydrological emergency current-measuring cableways have disadvantages such as cumbersome and time-consuming installation, disassembly and transportation to varying degrees, and cannot be reused, etc., and it is difficult to meet the requirements of mobility and portability for hydrological emergency current measurement, which affects the normal and efficient development of hydrological emergency measurement. In the prior art, there is still a lack of a safe, labor-saving, installation-free, mobile and portable hydrological emergency current-measuring cableway. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems of insufficient mobility and portability of the existing hydrological emergency current-measuring cableway, which may delay the measurement opportunity, and provide a mobile and portable box-type hydrological emergency current-measuring cableway. This device has a high integration degree, quick erection, high mobility and good portability, and effectively solves the problem that hydrological emergency measurement cannot be carried out when there are no cableways or water-crossing facilities such as bridges.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A mobile and portable box-type hydrological emergency flow measurement cableway, including a box body. Inside the box body, a reel base is arranged at one end. A main reel and a secondary reel are coaxially arranged on the reel base. The ends of the main reel shaft and the secondary reel shaft are aligned and are provided with a detachable coupling. The same steel wire rope is wound on the main reel and the secondary reel. One end of the steel wire rope is wound forward on the main reel, and the other end of the steel wire rope is wound backward on the secondary reel. A traction wheel is sleeved in the middle of the steel wire rope, and the traction wheel is fixed on the opposite bank of the river. At the top of the end wall of the box body corresponding to the reel base, two guiding wheels are installed, and the two sections of the steel wire rope extending from the main reel and the secondary reel are respectively placed on the guiding wheels.

[0007] Preferably, a driving motor is arranged at the end of the main reel shaft opposite to the coupling. A storage battery for supplying power to the driving motor is also arranged inside the box body. The main reel shaft and the driving motor are driven by a belt. A detachable hand crank is also arranged at the end of the main reel shaft.

[0008] Preferably, a counterweight block is arranged at the bottom inside the box body. A ground nail hole is opened at one end of the counterweight block away from the reel base, and the ground nail hole penetrates the bottom surface of the box body. The counterweight block can be arranged as a whole at the bottom of the box body, and the reel base is installed on the counterweight block to ensure that the counterweight block has sufficient volume and weight.

[0009] Preferably, the bottom surface of the box body adopts an uneven corrugated surface or a spiked surface.

[0010] Preferably, a guiding wheel hole is arranged at the top of the end wall of the box body where the guiding wheel is installed, and the guiding wheel and the guiding wheel hole are connected by detachable threads.

[0011] Preferably, an extension rod for raising the running height of the steel wire rope is arranged between the bottom of the guiding wheel and the top of the end wall of the box body.

[0012] Preferably, a storage box is arranged at one end of the box body away from the reel base. The storage box is used to store the guiding wheel and the traction wheel, and ground nails and thin ropes are also stored in the storage box.

[0013] Preferably, the steel wire rope is provided with scales, and the scales change color every fixed length interval.

[0014] Preferably, the top surface and one side surface of the box body are an integrated flip cover.

[0015] The rapid erection method of the above-mentioned mobile and portable box-type hydrological emergency flow measurement cableway includes the following steps:

[0016] S1. Arrive at the measurement location and stabilize the box on one side of the riverbank. Orient the end of the box with the directional wheel holes towards the river cross-section, and increase the stability of the box when it is pulled by the steel wire rope by driving ground nails into the ground at the ground nail holes. Counterweights are provided inside the box to increase the weight of the box and further enhance stability. When measuring the flow in a river with relatively rapid water flow, additional stability during box operation can be further enhanced by pressing stones on the counterweights, driving ground nails around the box and pulling the box with thin ropes, or pulling the box with the aid of trees or buildings.

[0017] S2. Determine the maximum measurable river width. Since the steel wire rope needs to run the flow measurement equipment from one bank to the other bank, that is, the steel wire rope needs to run a length of 1 river width, and the length of the steel wire rope laid across the river is 2 river widths. Therefore, the length of the steel wire rope should be at least 3 times the river width, that is, the maximum width of the river section to be measured should not be greater than 1 / 3 of the total length of the steel wire rope.

[0018] S3. Lay the steel wire rope across the river. Install the two directional wheels on the two directional wheel holes respectively, rotate the coupling to separate the main drum shaft from the auxiliary drum shaft, pull out the steel wire ropes from the main drum and the auxiliary drum respectively. After the pulled steel wire ropes pass through the directional wheels, they are sleeved onto the traction wheels on the opposite bank. When laying across the river, one end of the thin rope is pulled or projected to the opposite bank through a bridge or a shooting gun. The other end of the thin rope is connected to the steel wire rope and the traction wheel, and the thin rope is pulled to drive the steel wire rope and the traction wheel across the river. The traction wheel is fixed at a visible position on the bank of the opposite side of the river by anchoring to the ground or binding to a fixed building or tree. When there are levees or other obstructions on the flow measurement cross-section that require increasing the running height of the steel wire rope, the height of the directional wheel is increased by installing an extension rod between the directional wheel hole and the directional wheel, thereby increasing the running height of the steel wire rope.

[0019] S4. Tighten the steel wire rope across the river. After the steel wire rope is laid across the river, it is in a slack state. It is necessary to take in the excess length of the steel wire rope to make the steel wire rope in a taut state. Keep the main drum shaft and the auxiliary drum shaft in a separated state, and drive the main drum shaft to wind up the steel wire rope by a hand crank or a motor. The steel wire rope is gradually wound around the main drum, and the auxiliary drum remains stationary. The length of the steel wire rope across the river gradually shortens. When the steel wire rope across the river is in a taut state, rotate the coupling to lock the main drum shaft and the auxiliary drum shaft to each other. At this time, the length of the steel wire rope across the river remains unchanged and is kept in a taut state, and the cableway laying work is completed.

[0020] S5. Install the flow measurement device. Before installing the flow measurement device, first drive the main drum shaft and the auxiliary drum shaft to rotate counterclockwise simultaneously by means of a hand crank or a motor, so that all the steel wire ropes are wound around the main drum, making full use of the length of the steel wire ropes to ensure that the flow measurement device can be operated to the opposite bank. Install the flow measurement device on the steel wire rope extending from the main drum near the river bank. The flow measurement device can be a moving ADCP or a non-contact flow measurement device such as a radar gun. When the flow measurement device is a moving ADCP, connect the moving ADCP on the water surface to the steel wire rope through a towing rope. When the flow measurement device is a non-contact flow measurement device such as a radar gun, directly install the non-contact flow measurement device on the steel wire rope through an installation component.

[0021] S6. Conduct flow measurement operations. Keep the main drum shaft and the auxiliary drum shaft in a mutually locked state. At this time, the auxiliary drum shaft can only perform coaxial movement following the main drum shaft, and the back-and-forth movement of the steel wire rope can be realized by driving the main drum shaft to rotate through a hand crank or a motor. When starting the flow measurement operation, drive the drum shaft to rotate clockwise. As the steel wire rope on the main drum gradually unwinds, the steel wire rope on the auxiliary drum gradually winds in, and the length of the cross-river steel wire rope remains unchanged. The flow measurement device installed on the steel wire rope gradually moves towards the opposite bank. When the flow measurement device reaches the opposite bank, drive the drum shaft to rotate in the reverse direction, and the flow measurement device starts to return. Through the scale on the steel wire rope, the position of the flow measurement device from the river bank can be accurately judged, realizing the accurate positioning of the measurement position and improving the measurement accuracy.

[0022] S7. Storage after completion of the operation. After the flow measurement is completed, move the flow measurement device to the shore, disassemble the flow measurement device from the steel wire rope, recover the towing wheel and the steel wire rope on the opposite bank of the river, rotate the coupling to separate the main drum shaft and the auxiliary drum shaft from each other, drive the main drum shaft to rotate counterclockwise through a hand crank or a motor, the steel wire rope gradually winds around the main drum, the auxiliary drum remains stationary, and the length of the cross-river steel wire rope gradually shortens. When all the steel wire ropes are wound around the main drum, rotate the coupling to lock the main drum shaft and the auxiliary drum shaft to each other, and the storage of the steel wire rope is completed. Sort out other components and put them into the box body. After covering the box cover, the box body can be pushed forward through the rollers, saving manual handling.

[0023] The utility model integrates the hydrological emergency flow measurement cableway and its components in a box body. By moving the coupling, the main drum shaft and the auxiliary drum shaft can be locked or separated from each other, realizing the rapid erection of the hydrological cableway and tensioning the steel wire rope, and realizing the back-and-forth movement of the steel wire rope across the river. The utility model adopts box-type integration. During operation, only one person is required to operate, which is free of assembly, convenient for transportation, and has strong mobility and portability. It effectively solves the problem that hydrological emergency measurements cannot be carried out when there are no crossing facilities such as cableways or bridges, especially has strong practical value in the breach of sudden floods and small watersheds, and greatly improves the timeliness of emergency measurements.

The guiding wheel and the guiding wheel hole are connected by a detachable thread. An extension rod 14 for raising the running height of the steel wire rope can be selectively provided between the bottom of the guiding wheel 12 and the top of the end wall of the box body.

A counterweight is provided inside the box body, which can increase the weight of the box body to further increase the stability. When measuring the flow in a river with relatively rapid water flow, the stability of the box body during operation can be further increased by pressing stones on the counterweight, or driving ground nails around the box body and pulling the box body with thin ropes, or pulling the box body by means of trees or buildings.

[0034] S2. Determine the maximum measurable river width. Since the steel wire rope needs to run the flow measurement equipment from one bank to the other bank, that is, the steel wire rope needs to run a length of 1 river width, and the length of the steel wire rope laid across the river is 2 river widths. Therefore, the length of the steel wire rope is at least 3 times the river width, that is, the maximum width of the measured river section should not be greater than 1 / 3 of the total length of the steel wire rope.

The other end of the thin rope is connected to the steel wire rope and the traction wheel. Pull the thin rope to drive the steel wire rope and the traction wheel across the river. The traction wheel is fixed at a visible position on the bank of the opposite side of the river by means of anchoring to the ground, binding to a fixed building or a tree, etc. When there is a levee or other obstruction on the flow measurement cross-section that requires increasing the running height of the steel wire rope, the height of the directional wheel can be increased by installing an extension rod between the directional wheel hole and the directional wheel, thereby increasing the running height of the steel wire rope.

[0036] S4. Tighten the cross-river steel wire rope: After the cross-river steel wire rope is laid across the river, it is in a slack state. It is necessary to take in the excess length of the steel wire rope to make the steel wire rope in a taut state. Keep the main drum shaft and the auxiliary drum shaft in a separated state. Drive the main drum shaft to wind up the steel wire rope by means of a hand crank or a motor. The steel wire rope is gradually wound around the main drum. The auxiliary drum is in a stationary state.

Install the flow measurement equipment on the steel wire rope extending from the main drum near the river bank. The flow measurement equipment can be a moving ADCP or a non-contact flow measurement equipment such as a radar gun. When the flow measurement equipment is a moving ADCP, connect the moving ADCP on the water surface to the steel wire rope through a towing rope. When the flow measurement equipment is a non-contact flow measurement equipment such as a radar gun, directly install the non-contact flow measurement equipment on the steel wire rope through an installation component.

[0038] S6. Conduct flow measurement operations; keep the main drum shaft and the auxiliary drum shaft in a mutually locked state. At this time, the auxiliary drum shaft can only perform coaxial movement following the main drum shaft. By rotating the main drum shaft with a hand crank or a motor, the reciprocating movement of the wire rope can be achieved.
